Jawab:

9. 4 ,2/5÷2,2×(1,3/4÷50%)= 7

10. 2,8÷(20%×1,1/4)÷0,5= 22,4

Penjelasan dengan langkah-langkah:

9

4 2/5 : 2,2 x (1 3/4 : 50%)

= 22/5 : 22/10 x (7/4 : 1/2)

= 22/5 x 10/22 x (7/4 x 2/1)

= 2 x 7/2

= 7

10

2,8 (20% × 1 1/4) : 0,5

= 2,8 (20/100 x 5/4) : 0,5

= 28/10 (100/400) : 5/10

= 112.000/5.000

= 112/5

= 22 2/5

= 22,4
