2 × 7 = 14
35 – 14 = 21
Question 7.
34 + 
= 92
Answer:
58
Explanation:
Given, 34 + = 92
Let us consider the blank space as ‘x’.
34 + x = 92
Subtract 34 on both sides.
34 + x – 34 = 92 – 34
x = 58

Question 10.
Fish Caught
|
Juan |
Maggi | Max | Erik | Aliki | Tia |
Jarome |
| 7 | 4 | 5 | 7 | 11 | 4 | 7 |
How many more fish did Aliki catch than Tia?
Answer:
7
Explanation:
Number of fish Aliki catch = 11
Number of fish Tia catch = 4
Number of fish Aliki catch more than Tia = Number of fish Aliki catch – Number of fish Tia catch
= 11 – 4
=7
Question 11.
If you roll a 6-sided die 12 times, how many times would you expect to get a 6?
Answer:
2 times.
Explanation:
The probability of getting 6 on first role = (1/6)
The probability of getting 6 when rolled twice = 6 × 6 = 36
Then, the probability of getting 6 is (6/36) = (1/6)
So, when the dice is rolled n times then n(1/6)
Given 12 times. so n = 12
12(1/6) = (12/6)= 2
2 times
Question 12.
Tina spends 25% of her day in school. She spends \(\frac{1}{3}\) of her day sleeping. She spends \(\frac{1}{8}\) of her time at soccer practice. How many free hours does Tina have during the day?
Answer:
7 hours
Explanation:
Tine spends 25% of her day in school
100% – 24 hours
25% – ?(x)
By cross multiplication.
x = (25 × 24) ÷ 100
x =600 ÷ 100
x = 6
so, she spends 6 hours in school.
She spends (1/3) of her day in sleeping.
(1/3) × 24 = 8 hours
She spends (1/8) of her time at soccer practice.
(1/8) × 24 = 3 hours
Total number of hours she spends= hours Tina spends at school + Hours she spend at sleeping + Hours she spends at soccer practice.
= 6 + 8 + 3
= 17
Free hours Tina has during the day = 24 hours – Total number of hours she spends
= 24 – 17
= 7 hours
