3
B.
6

Explanation 1/6 (x) = 2 is the equation we will create. To solve for how many one-sixths make 2, we will multiply both sides by the reciprocal of 1/6 which is 6. Once we multiply both sides by 6, we are left with 2 x 6 = 12. Thus 12 one-sixths makes 2.

A.
0.003
B.
0.3
C.

D.

Correct Answer D. 0.03
Explanation In the case of "three hundredths," it means we have three parts out of 100 parts (since "hundredths" refers to dividing something into 100 equal parts). To represent this in decimal form, we write "0." (zero followed by a decimal point) to indicate that we are dealing with a fraction of 1, and then we add "03" to show that we have three parts out of 100. Therefore, "three hundredths" is written as "0.03" in decimal form.
