Question

1. solve $d - \frac{3}{8} = \frac{4}{8}$. $d = \square$

Explanation:

Step1: Isolate $d$ by adding $\frac{3}{8}$

$d - \frac{3}{8} + \frac{3}{8} = \frac{4}{8} + \frac{3}{8}$

Step2: Add the fractions on right

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

Step3: Simplify the numerator

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

Answer:

$\frac{7}{8}$
