B. 2/72, or 1/36.
C. 13/12, or 1 1/12.
D. 4/12, or 1/3.

Answer 1

The easiest way to add fractions is to get a common denominator. This can be done by multiplying by 1 expressed in whichever form is convenient.

For example

\[\frac{1}{6} = \frac{1}{6}\times\frac22 = \frac2{12}\]

So if you get the other two fractions to have a denominator of 12, it should be easy to sum them

Answer 2

is it C.

Answer 3

Yep :)
\[\frac{2 + 8 + 3}{12} = \frac{13}{12}\]
