1) 3 per 4 + 1 dua per 5 = 2) 2 per 8 - 3 satu per 7 = 3) 0,4 : 3 per 5 = 4) 1 dua per 4 : 2 satu per 3 = 5) 0,6 × 3 per 9 = ... Jawab yaa.. Tolongg!!

1. 3/4 + 1 dua/ 5 = 3/ 4 + 7/5
= 15/20 + 28/20
= 43/20
= 2 tiga/ 20

2. 2/8 - 3 satu/ 7 = 2/8 - 22/7
= 14/56 - 176/ 56
= ( - 162 ÷ 2 )/ ( 56 ÷ 2)
= -81/28
= -2 dua puluh lima/28

3. 0,4 ÷ 3/5 = 2/5 ÷ 3/5
= 2/5 × 5/3
= ( 10 ÷ 5 )/( 15 ÷ 5 )
= 2/3

4. 1 dua/4 ÷ 2 satu/3 = 6/4 ÷ 7/3
= 6/4 × 3/7
= ( 18 ÷ 2)/( 28 ÷ 2 )
= 9/14

5. 0,6 × 3/9 = 3/5 × 3/9
= ( 9 ÷ 9 )/( 45 ÷ 9 )
= 1/5
