A ratio is written in the form a : b. In this case, there are 6 gray keys for every 7 blue keys. So the ratio for gray to blue keys would be 6:7.
Since 6 and 7 don't have common factors, the ratio 6:7 cannot be simplified further.
So the ratio for gray to blue keys is 6:7.
A. 2x3=6 and 6x12=72 so 78 is greater than 36
6+72=79 which is less than 90
Question 1
Total budget = 180 + 475 + 15 + 50 + 65 + 25 + 150 + 30 = $990
Real spending = 182 + 475 + 12 + 65 + 68 + 12.50 + 150 + 36 = $1000.5
Mae Green didn't stay within the allocated budget

Question 2
Eleanor:
Income = 380.48
Spending = 16.50
Peter:
Income = 120 + 13.65 + 100 = 233.65
Total income = 233.65 + 380.48 - 16.50 = 597.63
-------------------------------------------------------------------------------------------------------------
Question 3
Total spent = 540 + 48.55 + 34.15 + 12.80 + 18.95 + 38.60 + 2 + 6.50 = 701.55
-------------------------------------------------------------------------------------------------------------
Question 4
Marie's new balance = 250.65 - [21.95+48.50+75.60] + 55 = $159.50
------------------------------------------------------------------------------------------------------------
Question 5
[235/825] × 100 = 28.48%
