Question

Hasil dri 1 3/4 - 1/5 + 4/8 × 7/5 adalah?

Answer 1

1 3/4 - 1/5 + 4/8 x 7/5
= 1 3/4 - 1/5 + 28/40
= 1 30/40 - 8/40 + 28/40
= 1 (30-8+28)/40
= 1 50/40
= 2 10/40
= 2 1/4

Answer 2

= 4/8 × 7/5 = 28/40
= 1 3/4 - 1/5 + 28/40
= 7/4 - 1/5 + 28/40
= 70/40 - 8/40 + 28/40
= 62/40 × 28/40
= 34/40 = 17/20 (dibagi 2)
