1. 3/4 × 5/8= 2. 1 2/2 - 1/2= 3. 2/3 + 4/5= 4. 5/5 × 3/5= 5. 4/7 - 2/7= 6. 5/7 × 3 2/5= 7. 1 3/2 : 4 2/8= 8. 2 2/4 × 1 2/9= 9. 4/5 : 1 2/3= 10. 2 1/4 × 7/8= tol

1.3/4 x 5/8 = 15/32
2. 1 2/2 - 1/2 = 4/2 - 1/2 = 3/2 = 1 1/2
3. 2/3 + 4/5 =  10/15 + 3/15 = 13/15
4. 5/5 x 3/5 = 15/5 = 3
5. 4/7 - 2/7 = 2/7
6. 5/7 x 3 2/5 = 5/7 x 12/5 = 60/35 = 12/7
7. 1 3/2  : 4 2/8 = 5/2 : 34/8 = 5/2 x 8/34 = 40/68 = 10/17
8. 2 2/4 x 1 2/9 = 10/4 x 11/9 = 110/36 = 55/18
9. 4/5 : 1 2/3 = 4/5 : 5/3 = 4/5 x 3/5 = 12/25
10. 2 1/4 x 7/8 = 9/4 x 7/8 = 63/32
itu jawabannya, kalau da yg gak ngerti dari mna hasilnya coment ajah nnti.

1) 15/32
2) 1 1/2
3) 10/15+12/15=22/15= 1 7/15

4) 3/5 (coret silang)
5) 2/7
6) 5/7x17/5 (coret silang) = 17/7= 2 3/7

7) 5/2:34/8= 5/2x8/34= 40/68= 10/17
8) 10/4x11/9= 110/36= 55/18= 3 1/18
9) 4/5:5/3= 4/5x3/5= 12/25

10) 9/4x7/8= 63/32= 1 31/32
