I need help with this problem:

Circle the number closest in value to 10.1

a. 9.9
b. 9.909
c. 10.99
d. 10.5

Think of these decimals as money.

10.1 is the same as $10.10.

Which of your answer choices is closest to a dollar and ten cents?

Which of your answer choices is closest to ten dollars and ten cents?

Is b. 9.909 correct?

Yes. In money, that would round to nine dollars and ninety-one cents.

thank you.

You're welcome.

To determine the number closest in value to 10.1, you need to compare the distance between each option and 10.1.

First, subtract 10.1 from each option to find the distance.

a. 9.9 - 10.1 = -0.2
b. 9.909 - 10.1 = -0.191
c. 10.99 - 10.1 = 0.89
d. 10.5 - 10.1 = 0.4

Next, look for the option with the smallest absolute value (the distance without considering the negative or positive sign). The option with the smallest absolute value will be the closest number to 10.1.

a. Absolute value of -0.2 is 0.2
b. Absolute value of -0.191 is 0.191
c. Absolute value of 0.89 is 0.89
d. Absolute value of 0.4 is 0.4

Therefore, the number closest in value to 10.1 is option a. 9.9.
