What is 9/16 + 1/2 simplified

trasher [3.6K]

$\frac{9}{16}$ + $\frac{1}{2}$

First, find the least common denominator (LCD) of the two fractions.
Multiples of 16: 16
Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16
The LCD is 16.
Second, make the denominators the same as the LCD. / Your problem should look like: $\frac{9}{16}$ + $\frac{1x8}{2x8}$
Third, simplify. The denominators are now the same. / Your problem should look like: $\frac{9}{16}$ + $\frac{8}{16}$
Fourth, join the denominators. / Your problem should look like: $\frac{9+8}{16}$
Fifth, simplify. / Your problem should look like: $\frac{17}{16}$
Sixth, convert to mixed fraction. / Your problem should look like: $1 \frac{1}{16}$

Answer: $1\frac{1}{16}$
