4/5 of 60=48 because the five or(fifth) divided 60=12 and 4 times 12=48 the answer is [48]
6 x 12 is multiplied to get 72 4 is subtracted from 72 to get the answer 68

4m + 12 = 604m + 12 -12 = 60 -12 (1st subtract 12 from both sides)4m = 484m/4 = 48/4 (now divide both sides by 4 to solve for m)m = 12
12-8 = 4 and 2*4 = 8
To add fractions, the denominators (bottom numbers) must be equal; so first convert the fractions into equivalent fractions with the same denominator. Then the numerators (top numbers) are added/subtracted and the resulting fraction simplified: lcm(4, 3, 5) = 60 60 ÷ 4 = 15 60 ÷ 3 = 20 60 ÷ 5 = 12 3/4 = (3×15)/(4×15) = 45/60 2/3 = (2×20)/(3×20) = 40/60 1/5 = (1×12)/(5×12) = 12/60 → 3/4 + 2/3 + 1/5 = 45/60 + 40/60 + 12/60 = (45+40+12)/60 = 97/60 = (1×60+37)/60 = 1 37/60
