20
20 = 1 x 20
100 = 5 x 20
10% as a decimal would be .10
For #3, it's 5.4 because you divide the total amount of money made by the amount of money earned per hour.
49.95/9.25=5.4 hours
The answer is 361.
This is because you take 731 and subtract 9 and you get 722. Then you divide 722 by two and you get 361.
Hope this helped!!
Answer as a fraction = 9/4
Answer in decimal form = 2.25
================================================
Explanation:
1/4 = 4/16 after multiplying top and bottom by 4
We have some number x such that
(4/16)x = 9/16
we can multiply both sides by 16 to clear out the fractions, getting 4x = 9
Then we divide both sides by 4 to get x = 9/4 = 2.25
