tolong ya soalnya besok udah mau di kumpulkan

14 1/6 - 2 7/15 =85/6 - 37/15
= 425/30 - 74/30
= 351/30
= 12 21/30 = 12 7/10

48/100 :18/25 = 48/100 × 25/18
= 16/24 = 4/6 = 2/3

13/8 × 11/5 = 65/40 × 88/40
=13/5 × 11/8
= 143/40 = 3 23/40

4/5 + 175/100 = 175/100 + 80/100
= 225/100 = 2 1/4

5/9 : 7/4 × 36/100 = 5/9 × 4/7 = 20/63
=20/63 × 36/100
= 12/105 = 4/35

maaf kalo salah
