mtk selesaikan operasi hitung berikut? tolong pakai cara ya

A.
3 ¾ + 2 1/6
= 15/4 + 13/6
= 45/12 + 26/12
= 71/12 = 5 11/12

B.
5 2/9 - 3 ½
= 47/9 - 7/2
= 94/18 - 63/18
= 31/18 = 1 13/18

C.
2 5/6 × 1 ⅓ =
17/6 × 4/3 = 68/18 = 3 14/18 = 3 7/9

D.
1 1/5 ÷ ¼
= 6/5 × 4/1
= 24/5 = 4 4/5

E.
2 × 4 3/8 - 5 ¾=
2/1 × 27/8 - 23/4
= 54/8 - 23/4
= 54/8 - 46/8
= 8/8 = 1

Maaf bila salahヾ(〃^∇^)ﾉ
