Question

Which of the following decimals is equal to 3 1/40 ? Select TWO that apply

Answer 1

Answers:  Choice B, Choice F

=======================================================

Explanation:

Use long division or your calculator to find that 1/40 = 0.025

Add on 3 to get 3 & 1/40 = 3 + 1/40 = 3 + 0.025 = 3.025 which is choice B

For some reason, your teacher has decided to add on a string of 0's onto this to form $3.025\overline{0}$ that horizontal line over the '0' means the 0's go on forever. So, $3.025 = 3.025\overline{0} = 3.025000000...$, but we can always chop off the trailing zeros to make life simpler. I'm not sure why your teacher has decided to use this fairly strange format.
