1. 3 5/8 x 4 2/5 = 2. 1 1/9 x 2 3/9 = 3. 2/3 x 0.4 = 4. 5/6 x 10% = 5. 1/4 x 20% = bagaimana cara penyelesaian nya pecahan campuran kepecahan biasa, tolong bant

1. 3 5/8 x 4 2/5
= 29/8 × 22/5
= 638/40
= 319/20 = 10 19/20

2. 1 1/9 x 2 3/9
= 10/9 × 21/9
= 210/81
= 70/27 = 2 16/27

3. 2/3 x 0.4
= 2/3×4/10
= 8/30
= 4/15 = 3 3/4

4. 5/6 x 10%
= 5/6×10/100
= 50/600
= 5/60 = 1/12

5. 1/4 x 20%
= 1/4×20/100
= 20/400
= 2/40 = 1/20

Semoga membantu
