Pecahan dari 1. 2 1/5 × 2 3/4 = 2.5 1/4 × 7 = 3. 7 1/2 : 1/4 = 4. 2/5 × 2/3 × 3/4 =

itu jawabannya
semoga membantu : )

1. 2 1/5 × 2 3/4 = 11/5 × 11/4
= 121/20
= 6 1/20
2. 5 1/4 × 7 = 21/4 × 7/1
= 147/4
= 36 3/4
3. 7 1/2 ÷ 1/4 = 15/2 ÷ 1/4
= 15/2 × 4/1
= 60/2
= 30
4. 2/5×2/3×3/4 = 2/5×2/1×1/4
= 4/5 × 1/4
= 4/20
=1/5
maaf kalau ada yang salah
