simplify 100%-9/10 — step-by-step solution

Let's reduce:

\frac{100}{100} - \frac{9}{10}

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

100

, the least common multiple of

100

and

10

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

\frac{100}{100} - \frac{9}{10}

\frac{100}{100} + \frac{-9 \times 10}{10 \times 10}

\frac{100 - 9 \times 10}{100}

\frac{100 - 9 \times 10}{100}

ⓘ Multiplications are done before additions and subtractions:

9 \times 10

90

\frac{100 - 90}{100}

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

100 - 90

10

\frac{10}{100}

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

10

, their greatest common divisor:

\frac{10}{100}

\frac{1 \times 10}{10 \times 10}

\frac{1}{10}

▶Simplified form:

\frac{1}{10}
