Question

Which is the same as dividing a number by 10?

a. 1,539 × 100
b. 153.9 ÷ 10
c. 1.539 ÷ 10
d. 100 ÷ 15.39

Answer 1

Explanation:

Both (b) and (c) represent "dividing a number by 10," where the number is either 153.9 or 1.539.

Reject (a) because 1539 is divided by 100 (not 10) here.

Reject (d) because it's 100 being divided by 15.39 (not by 10).
