Question

Rounding to the nearest​ tenth, which of the following give an​ underestimate?

A.16.48 times 3.16
B.32.27 times 2.3
C.5.62 times 2.34
D.17.44 times 0.63
E.67.06 times 4.58

Answer 1

Option D, 17.44 times 0.63, gives an underestimate when rounded to the nearest tenth.

Step-by-step explanation:

In order to determine which of the given options provides an underestimate when rounded to the nearest tenth, we need to consider the first decimal place after the tenths place. If this digit is less than 5, we round down. If it is greater than or equal to 5, we round up. Let's apply this to each option:

A. 16.48 times 3.16 = 51.7648, which rounds down to 51.8

B. 32.27 times 2.3 = 74.421, which rounds up to 74.4

C. 5.62 times 2.34 = 13.1328, which rounds up to 13.1

D. 17.44 times 0.63 = 10.9872, which rounds down to 11.0

E. 67.06 times 4.58 = 307.3848, which rounds up to 307.4

From the above calculations, we can see that option D, 17.44 times 0.63, gives an underestimate when rounded to the nearest tenth.
