Question 6.
17 – 22 × 5 = __________
Answer:
17 – 22 × 5
= 17 – 4 × 5
= 17 – 20
= -3
Explanation:
First perform operation on the square of 2. The square of 2 is 4. Now the expression is 17 – 4 × 5.
Second perform multiplication operation on above expression. Multiply 4 with 5 the product is 20. Now the expression is 17 – 20.
Next perform subtraction operation. Subtract 20 from 17 the difference is -3.
Question 7.
Find k.
k – \(\frac{3}{11}\) = \(\frac{4}{11}\)
k = __________
Answer:
k – \(\frac{3}{11}\) = \(\frac{4}{11}\)
k = 4/11 + 3/11
k = 7/11
Explanation:
To calculate k value we need to perform addition operation on above given equation. Add 3/11 to 4/11 the sum is 7/11. The value of k is equal to 7/11.
Question 8.
Find r.
r + \(\frac{1}{4}\) = \(\frac{3}{4}\)
r = _________
Answer:
r + \(\frac{1}{4}\) = \(\frac{3}{4}\)
r = 3/4 – 1/4
r = 2/4
r = 1/2
Explanation:
To calculate r value we need to perform subtraction operation on above given equation. Subtract 1/4 from 3/4 the difference is 2/4. The simplified form of 2/4 is 1/2. The value r is equal to 1/2.
Question 9.
Calculate the distance a car can travel in 7 hours at 150 \(\frac{Km}{h}\).
Answer:
In one hour the car can travel a distance of 150 km.
1 hour = 150 km
7 hours = ? Km
(150 km x 7 hours)/1 hour = 1,050 km
A car can travel 1,050 km in 7 hours.

Question 11.
Inside a bag of candy are 16 lollipops, 12 pieces of chocolate, and 7 pieces of licorice. If you reach ¡n the bag and grab a piece of candy, what is the probability that it will either be licorice or a lollipop?
Answer:
Total lollipops are 16.
Total piece of chocolates are 12.
Total pieces of licorice are 7.
Total number of candies are 16 + 12 + 7 = 35
Total number of lollipops and a piece of licorice are 23.
16 + 7= 23
The probability of either a lollipop or a piece of chocolate is 23/35.
