Question

Find the sum of $1\frac{5}{6}$ and $\frac{13}{36}$

• A. $1\frac{43}{36}$
• B. $2\frac{1}{36}$
• C. $2\frac{7}{36}$
• D. $2\frac{13}{36}$

Answer 1

The correct option is C

$2\frac{7}{36}$

Sum of $1\frac{5}{6}$ and $\frac{13}{36}$

= $1\frac{5}{6}$ + $\frac{13}{36}$

= $\frac{11}{6}$ + $\frac{13}{36}$

LCM of 6 and 36 is 36

So, $\frac{11}{6}$ + $\frac{13}{36}$ = $\frac{11\times 6}{6\times 6}$ + $\frac{13}{36}$

= $\frac{66+13}{36}$

= $\frac{79}{36}$

= $2\frac{7}{36}$
