If you take 208.56 and divide it by 100 you can find 1%, which is 2.0856 if you now multiply it by 15 you can find 15%, which is 31.284. Now all you need to do is subtract 31.284 (15%) from 208.56, which gives you 177.276

523 subtracted from 415 eaves you with a negative number of -108. If that's 5 and 2/3 - 4 and 1/5 17/3 - 21/5 85/15 - 63/15 = 22/15 = 1 and 7/15

1. Subtract 25 2. Then subtract 6 3. Then subtract 12 4. Then subtract 2 5. Then subtract 10 6. Then subtract 15 7. Then subtract 7 8. Then add 3 X 1/2 9. Then add 8

= [Cell]*(1-x%) e.g. = A1*(1-15%)

First, to subtract fractions, you need to make sure that the both have a common denominator. By this, I mean that they need to have the same number on the bottom of the fraction. If they are not the same, you need to multiply. Say you had this problem: 4/5 - 1/3 You will notice they don't have a common denominator. To make sure that the bottom is the same number, multiply 4/5 by 3 and 1/3 by 5. When you multiply, you do this to both the top and the bottom number. The problem now looks like this: 12/15 - 5/15 Now you're ready to subtract! All you have to do is subtract the top numbers, and keep the bottom ones the same. So: 4/5 - 1/3 = 7/15

The GCF of 12 15 and 22 is 1.

22 - 12 = 4 - 1 = 3

22 divided by 15 equals 1 with a remainder of 7.

22

Method 1: 75 - 31 = 44, half of 44 is 22 which is the smaller number so the larger is 53. Method 2: 75 = 38 + 37, difference 1. Add 15 to 38 and subtract 15 from 37 and you get 53 and 22. The choice is yours...
