Can some help and explain this please? ​

Answer 1

a. 10³ × 0.005 =5

a. 10²×0.005=0.5

b . 0.09×10 = 0.9

b. 0.009 ×10³ = 9

Explanation:

a. ___ × 0.005 = 5 —> 5 ÷ 0.005 = 1000 So; 1000 = 10³

a. ___ × 0.005 = 0.5 —> 0.5÷0.005=100 So; 100=10²

b. 0.09 × ___=0.9 —> 0.9 ÷ 0.09= 10 So; 10

b. 0.009 × ___=9 —> 9÷ 0.009= 1000 So; 1000=10³

I hope I helped you^_^
