I need homework help! :(

Reduce 18 (over) 20 , 23 (over) 46 , and 7 over 14 to lowest terms 9 (over) 10 , 1 (over) 2 ,1 (over) 4 , 1 (over) 2

18/20 = 9/10
23/46 = 1/2
7/14 = 1/2

compare 9/10 , 1/2, 1/4, 1/2 multiply the fractions to have the same denominator

18/20, 10/20, 5/20, 10/20 so the lowest is 5/20 = 1/4

18/20 ----> 9/10 after dividing both numerator and denominator by 2
23/46 -----> 1/2 after dividing both by 23
7/14 -----> 1/2 after dividing both by 7

18/20 = 9/10
23/46 = 1/2
7/14 = 1/2
