3 1 per 5 × 2 3 per 4 : 4 1 per 2 Plizz jawab pakai cara yang jelas Dan 4 2 per 5 : 1 1 per 4 - 2 3 per 5

3 1/5 = 16/5
2 3/4 = 11/4
4 1/2 = 9/2

16/5 x 11/4 = 176/20 = 88/10 = 44/5

44/5 : 9/2 = 44/5 x 2/9 = 88/45 = 1,955555

3 1/5 × 2 3/4 ÷ 4 1/2
= 16/5 × 11/4 ÷ 9/2
= 176/20 ÷ 9/2
= 176/20 × 2/9
= 352/180
= 1 172/180
= 1 86/90
= 1 43/45

4 2/5 ÷ 1 1/4 - 2 3/5
= 22/5 ÷ 5/4 - 13/5
= 22/5 × 4/5 - 13/5
= 88/25 - 13/5
= 88/25 - 65/25
= 23/25
