1/18+9/14

Let's evaluate:

\frac{1}{18} + \frac{9}{14}

ⓘ Add fractions by using a common denominator and then adding their numerators. We choose

126

, the least common multiple of

18

and

14

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

\frac{1}{18} + \frac{9}{14}

\frac{1 \times 7}{18 \times 7} + \frac{9 \times 9}{14 \times 9}

\frac{1 \times 7 + 9 \times 9}{18 \times 7}

\frac{7 + 9 \times 9}{18 \times 7}

\frac{7 + 9 \times 9}{18 \times 7}

126

\frac{7 + 81}{126}

ⓘ Calculate the numerator and denominator before dividing:

7 + 81

88

\frac{88}{126}

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

2

, their greatest common divisor:

\frac{88}{126}

\frac{44 \times 2}{63 \times 2}

\frac{44}{63}

▶Result:
