1 ) Find the difference of (3/16) - (1/20) =
in order to do the subtraction we first take the LCM of the denominators. The LCM is calculated by breaking down the denominator into lowest terms
16 = 2 x 2 x 2 x 2
20 = 2 x 2 x 5
now lcm = 2 x 2 x 5 x 2 x 2 = 80 [calculated at the product of unique numbers in the breakdown of each denominator]
now 3/16 can be re written as 15/80 (multiplying both numerator and denominator by 5)
1/20 can be written as ...
