$\frac{7}{8}$ $7/8$

Explanation:

The solve the calculation, both numerator and denominator of $\frac{1}{2}$ $1/2$ is multiplied by $4$ $4$ so that its denominator is equal to $8$ $8$ . And the
you can solve directly the calculation;

$= (\frac{1}{2} \times \frac{4}{4}) + \frac{3}{8}$ $=(1/2xx4/4)+3/8$

$= \frac{4}{8} + \frac{3}{8}$ $=4/8+3/8$

$= \frac{7}{8}$ $=7/8$

The answer is $\frac{7}{8}$ $7/8$ .

Explanation:

In order to add fractions, the denominators must be the same.

$\frac{1}{2} + \frac{3}{8}$ $1/2+3/8$

Find the least common denominator by prime factorization.

$2 : 2$ $2 : color(red)2$

$8 : 2, 2, 2$ $8 : color(red)2, color(blue)2, color(blue)2$

To determine the least common denominator (LCD), multiply the common factor $2$ $color(red)2$ times the other factors in blue.

LCD $=$ $=$ $2 \times 2 \times 2 = 8$ $color(red)2xxcolor(blue)2xxcolor(blue)2=8$

Multiply $\frac{1}{2}$ $1/2$ times $\frac{4}{4}$ $4/4$ so that it will have a denominator of $8$ $8$ .

$\frac{1}{2} \times \frac{4}{4} + \frac{3}{8} =$ $1/2xx4/4+3/8=$

$\frac{4}{8} + \frac{3}{8} = \frac{7}{8}$ $4/8+3/8=7/8$
