Mr. Chou makes fruit salad that he sells in his store. Today he plans to make a fruit salad with 8 pears, 2 cups of grapes, and 4 pints of strawberries. Use the weights below to solve the problems.

  • A medium pear weighs about \(\frac{3}{8}\) lb.
  • A cup of grapes weighs about \(\frac{2}{8}\) lb.
  • A pint of strawberries weighs about \(\frac{5}{8}\) lb.

Question 1.
Write a multiplication sentence to show how much the pears weigh. ___
Answer: __ pound(s)
Total Weight of 8 pears = 3 pounds .
Explanation :
Number of pears = 8
Weight of each pear = \(\frac{3}{8}\) lb.
Total Weight of 8 pears = Number of pears × Weight of each pear = 8 ×  \(\frac{3}{8}\) = 3 lbs .
1 lbs = 1 pound
3 lbs = 3 pounds.
Therefore, Total Weight of 8 pears = 3 pounds .

Question 2.
Write a multiplication sentence to show how much the grapes weigh. ___
Answer: __ pound(s)
Total Weight of 8 pears = 2 pounds .
Explanation :
Number of cups of grapes = 2 cups
Weight of each cup = \(\frac{2}{8}\) lb.
Total Weight of 2 cups of grapes = Number of cups of grapes × Weight of each cup of grapes = 2 ×  \(\frac{2}{8}\) = 2 lbs .
1 lbs = 1 pound
2 lbs = 2 pounds.
Therefore, Total Weight of 2 cups of grapes = 2 pounds .

Question 3.
Write a multiplication sentence to show how much the strawberries weigh. ____
Answer: ___ pound(s)
Total Weight of 4 pints of strawberries = 2\(\frac{1}{2}\) pounds .
Explanation :
Number of pints of strawberries = 4
Weight of each pint of strawberries = \(\frac{5}{8}\) lb.
Total Weight of 4 pints of strawberries = Number of pints of strawberries × Weight of each pint of strawberries = 4 × \(\frac{5}{8}\) =  \(\frac{5}{2}\) lbs  = 2\(\frac{1}{2}\) lbs
1 lbs = 1 pound
2\(\frac{1}{2}\) lbs = 2\(\frac{1}{2}\) pounds.
Therefore, Total Weight of 4 pints of strawberries = 2\(\frac{1}{2}\) pounds .

Question 4.
How much does Mr. Chou’s salad weigh in all? Show your work.
Answer:
Total weight of salad = 7\(\frac{1}{2}\) pounds.
Explanation :
Total Weight of 8 pears = 3 pounds .
Total Weight of 2 cups of grapes = 2 pounds .
Total Weight of 4 pints of strawberries = 2\(\frac{1}{2}\) pounds .
Total Weight of salad = 3 + 2 + 2\(\frac{1}{2}\) = 5 + 2\(\frac{1}{2}\) = 5 + 2 + \(\frac{1}{2}\)= 7 + \(\frac{1}{2}\) = 7\(\frac{1}{2}\) pounds.
Therefore, Total weight of salad = 7\(\frac{1}{2}\) pounds.

Package ___ charges $ ___ more per ticket.
Answer:
Cost of Package A = $276
Number of tickets = 2 tickets for each of 6 games = 2 × 6 = 12 tickets
Cost of each ticket in Package A = $276 ÷ 12 = 23$ .
Cost of Package B = $336
Number of tickets = 2 tickets for each of 8 games = 2 × 8 = 16 tickets
Cost of each ticket in Package A = $336 ÷ 16 = 21$ .
Package A costs more per ticket . More charge per ticket = 23$ – 21$ = 2$ .

Question 2.
Rebecca wants to put 544 pennies in a coin-collection book. The blue book fits 9 pennies per page. The red book fits 7 pennies per page. How many more pages would she need if she used the red book rather than the blue one?

The red book will take __ more pages than the blue book.
What did you do with any remainders you found?
Answer:
Total Number of Pennies = 544 pennies
Number of pennies in one page of blue book = 9 pennies per page
Number of pages required for 544 pennies in Blue book= 544 ÷ 9 = 60\(\frac{4}{9}\) pages .
Number of pennies in one page of Red book = 7 pennies per page
Number of pages required for 544 pennies in Red book = 544 ÷ 7 = 77\(\frac{5}{7}\) pages .
Number of More pages Red will take than Blue book = 77\(\frac{5}{7}\) – 60\(\frac{4}{9}\) = 77 + \(\frac{5}{7}\) – 60 – \(\frac{4}{9}\) = 17 + \(\frac{45}{63}\) – \(\frac{28}{63}\) = 17 + \(\frac{17}{63}\) = 17\(\frac{17}{63}\) .

Use the information in the table below to solve the number stories.
During Marcy School’s 2-week challenge, each student who meets a goal wins a prize.
Everyday Math Grade 4 Home Link 7.10 Answer Key 40.8

Question 1.
Tony will run \(\frac{1}{2}\) mile after school each day. Will he win a prize?
a. Distance run in 1 week: mile(s)
b. In 2 weeks: mile(s)
Explain how you found your answer.
Answer:
a.
Distance run by Tony each day = \(\frac{1}{2}\) mile
Number of days for 1 week = 5 days .
Distance run in 1 week = 5 × \(\frac{1}{2}\) = \(\frac{5}{2}\) = 2\(\frac{1}{2}\) miles .
b.
Distance run by Tony each day = \(\frac{1}{2}\) mile
Number of days in 2 weeks = 2 × 5 = 10 days
Distance run in 2 weeks = 10 × \(\frac{1}{2}\) = 5 miles .
To win a prize distance run should be 4 miles .
In 2 weeks tony runs 5 miles that means 5 > 4 . So, Tony will win a prize .

Question 2.
Three times a week, Tina walks \(\frac{3}{10}\) mile from school to the library, studies for 1 hour,
and then walks \(\frac{4}{10}\) mile home. How much more will she need to walk to win a prize?
____ mile(s)
Explain how you found your answer.
Answer:
Number of days in a week = 3 days .
Distance walk by Tina from school to library  = \(\frac{3}{10}\) mile
Distance walk by Tina from library to home =  \(\frac{4}{10}\) mile
Total Distance Tina walks for a day  = \(\frac{3}{10}\) + \(\frac{4}{10}\) mile = \(\frac{7}{10}\) mile .
Total Distance Tina walks for 3 days or 1 week = 3 × \(\frac{7}{10}\) = \(\frac{21}{10}\) miles = 2.1 miles .
Total Distance Tina walks for 2 weeks = 2 × 2.1 = 4.2 miles .
To win a prize distance walk should be 6 miles .
2.1 < 6 miles that means she doesnot win a prize .
Therefore, Tina doesn’t receive a prize .
