To divide 1.89 : 0.9, we need to change it. Choose the correct problem below to show what the "new" look would be.

A. 189 : 9

B. 18.9 : 0.9

C. 1.89 : 9

D. 18.9 : 9

D. 18.9 : 9

Step-by-step explanation:

we need to divide

1.89 : 0.9 but write it in different form

so, we need to eliminate decimal from 0.9

as 0.9*10 = 9

thus, we multiply both 1.89 and 0.9 with 10, then we will have

(1.89*10) : (0.9*10)

=> 18.9 : 9

Thus, based on above calculation new look would be D. 18.9 : 9
