6/7+9/14

Let's calculate:

\frac{6}{7} + \frac{9}{14}

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

14

, the least common multiple of

7

and

14

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

\frac{6}{7} + \frac{9}{14}

\frac{6 \times 2}{7 \times 2} + \frac{9}{14}

\frac{6 \times 2 + 9}{14}

\frac{6 \times 2 + 9}{14}

ⓘ Perform multiplications before additions and subtractions:

6 \times 2

12

\frac{12 + 9}{14}

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

12 + 9

21

\frac{21}{14}

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

7

, their greatest common divisor:

\frac{21}{14}

\frac{3 \times 7}{2 \times 7}

\frac{3}{2}

▶Result:

\frac{3}{2}

The numeric value of:

\frac{3}{2}

equals:
