Question

The product 0.37 x 4.8 is equivalent to

• A. 3.7 x 0.48
• B. 0.037 x 4.8
• C. 0.37 x 0.48
• D. 37 x 0.048

Answer 1

Answer: (A), (D)

The correct options are
A

3.7 x 0.48

D

37 x 0.048

0.37 x 4.8 = 1.776

3.7 x 0.48 = 1.776

37 x 0.048 = 1.776

This can be answered without actual multiplication since the total number of digits after the decimal point is 3 in both 0.37 x 4.8 and in 3.7 x 0.48.

Whereas 0.037 x 4.8 and 0.37 x 0.48 have 4 digits after the decimal point, and hence their product cannot be equal to 0.37 x 4.8
