Peter’s solution: 10% of $55 is $5.50. so subtract 100% − $5.50 = $94.50. some more mental math tricks: 90% of a quantity. first find 10% of the quantity and then subtract that 10% from 100% of it. 25% of a quantity. 25% is the same as 1 4. so to find 25% of a quantity, divide it by 4. Now here comes the cool part: the associative property of multiplication tells us that we can multiply several numbers in any order we’d like. which means that (0.01 x 36) x 25 = (0.01 x 25) x 36. but 0.01 x 25 is the same thing as 25%, which means that this is equal to 25% of 36. so 36% of 25 is equal to 25% of 36.
