simplify 1/2+3/8-1/8 — step-by-step solution

Let's simplify:

\frac{1}{2} + \frac{3}{8} - \frac{1}{8}

ⓘ To add fractions, put them over the same denominator, then add the numerators. We choose

8

, the least common multiple of

2

and

8

. Multiplying the numerator and the denominator by the same number does not change the fraction:

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

\frac{1 \times 4}{2 \times 4} + \frac{3}{8}

\frac{1 \times 4 + 3}{8}

\frac{4 + 3}{8}

\frac{4 + 3}{8} - \frac{1}{8}

ⓘ The numerator and the denominator are computed before the division:

4 + 3

7

\frac{7}{8} - \frac{1}{8}

ⓘ To add fractions, put them over the same denominator, then add the numerators:

\frac{7}{8} - \frac{1}{8}

\frac{7 - 1}{8}

\frac{7 - 1}{8}

ⓘ The numerator and the denominator are computed before the division:

7 - 1

6

\frac{6}{8}

ⓘ We simplify the fraction by dividing the numerator and the denominator by

2

, their greatest common divisor:

\frac{6}{8}

\frac{3 \times 2}{4 \times 2}

\frac{3}{4}

▶Simplified form:

\frac{3}{4}

The numeric value of:

\frac{3}{4}
