Find the value of this fraction 6 x 1/2 + 2/3 + 3/4

kodGreya [7K]

Answer:

$\frac{53}{12} or 4 \frac{5}{12}$

Step-by-step explanation:

$\frac{6}{1} \times \frac{1}{2} = 3$

$\frac{3}{1} + \frac{2}{3} + \frac{3}{4} = ...$

Find the common denominator, which is 12

$\frac{36}{12} + \frac{8}{12} + \frac{9}{12} =$

Now add them

$\frac{36}{12} + \frac{8}{12} = \frac{44}{12} + \frac{9}{12} = \frac{53}{12}$

Simplified version is

$4 \frac{5}{12}$
