Mohon Di jawab skng

Answer 1

5¼ + 3 = 21/4 + 3/1 = 21/4 + 12/4 = 33/4 = 8¼

5 3/5 - 2¼ = 28/5 - 9/4 = 112/20 - 45/20 = 67/20 = 3 7/20

2 2\6 × 2 4\10 = 14/6 × 24/10 = 14 × 4/10 = 5,6

1 6\9 : 3 2\6 = 15/9 × 6/20= ½ atau 0,5

8 3\5 + 3,75:(3 1\2 - 1 5\6
= 43/5 + 375/100 : 7/2 - 11/6
= 43/5 + 15/4 : 7/2 - 11/6
= 43/5 + 15/4 × 2/7 - 11/6
= 43/5 + 15/14 - 11/6
= 602/70 + 75/70 - 11/6
= 677/70 - 11/6
= 2031/210 - 385/210
= 1646/210
= 7,83
