A 3 6/8 - 2 1/3 B 6× 3 2/3 C 3 8/10 ×2 5/7 D8/10 ÷ 2 6/9 E 3/5 : 2 6/9 TOLONG

A) 3 6/8 - 2 1/3
= 30/8 - 7/3
= 30/8 dikali 3 - 7/3 dikali 8
= 90/24 - 56/24
= 34/24 diperkecil menjadi 17/12
= 1 5/12

B) 6 × 3 2/3
= 6 × 11/3
= 66/3
= 22

C) 3 8/10 × 2 5/7
= 38/10 × 19/7
= 722/70 diperkecil menjadi 361/35
= 10 11/35

D) 3/5 : 2 6/9
= 3/5 : 24/9
= 3/5 × 9/24
= 27/120 diperkecil menjadi 9/40
