tolong jawab dari no 1 sampek no 6 pakek caraaa soalny bsk di kumpul plis jawab jadiin pecahan biasa ok

1.4/8+3/7-4/5 =

4/8+3/7=28/56+24/56=52/56=26/28=13/14

13/14 - 4/5 = 130/140 - 112/140 = 18/10

2.2 3/5 - 2/3 =

13/5 - 2/3 = 29/15
= 1 14/15
3.2 2/5 + 1/4 =

12/5 + 1/4 = 48/20 + 5/20 = 43/20
= 2 3/20
4.1 4/7 × 5/9 =

11/7 × 5/9 = 55/63
5.2/3 ÷ 5 1/8 =

2/3 ÷ 41/8 = 2/3 × 8/41 = 16/123
6.1/8 ÷ 5/7 × 4/21

1/8 ÷ 5/7 = 1/8 × 7/5 = 7/40

7/40 × 4/21 = 28/840 = 14/420 = 7/210 = 1/30
