I cha use a 10 fact because I can round to the nearest 10 which is 20 for 15 and 10 for 8
0.45 Isn't Equal To Any Of These Fractions But It Is Equal To 45/100
Because it's decreasing, you use the formula (1-x/100)y with x the percentage decreased which is here 40, and y the number decreased which is here 90
So we get
(1-40/100) * 90
(100/100 - 40/100) * 90
60/100 * 90
5400/100
54
So 90 decreased by 40% is 54
Hope this Helps :)
3/5 = 6/10 (which is 60%) 100% - 60% = 40%
