6 - 15/40 = 0.375 = 37.5%
When looking to convert a decimal to a percent you move the decimal over two places so, 0.375 becomes 37.5
8 - 70*1.2 = 80
You see 100% is equal to 1.00 when multiplying/dividing. So 1.2 = 120%
10 - 48*0.25 = 12 and 12+48 = 60 So, 60.
Here, we use 0.25 because 100% - 75% = 25% or... 1.0 - 0.75 = 0.25
