subtract the fractions with like denominators without a calculator. reduce to simplest form. $\frac{13}{16}-\frac{7}{16}$

Explanation:

Step1: Add numerators, keep denominator

$\frac{2}{9} + \frac{7}{9} = \frac{2+7}{9}$

Step2: Simplify the sum

$\frac{9}{9} = 1$

Step3: Subtract numerators, keep denominator

$\frac{13}{16} - \frac{7}{16} = \frac{13-7}{16}$

Step4: Simplify the difference

$\frac{6}{16} = \frac{3}{8}$

Answer:

1. $1$
2. $\frac{3}{8}$
