Question

7/9-5/12 equation sum​

Answer 1

Find the Least Common Denominator (LCD) of \frac{7}{9},\frac{5}{12}

9

7

,

12

5

. In other words, find the Least Common Multiple (LCM) of 9,129,12.

LCD = 3636

2 Make the denominators the same as the LCD.

\frac{7\times 4}{9\times 4}-\frac{5\times 3}{12\times 3}

9×4

7×4

−

12×3

5×3

3 Simplify. Denominators are now the same.

\frac{28}{36}-\frac{15}{36}

36

28

−

36

15

4 Join the denominators.

\frac{28-15}{36}

36

28−15

5 Simplify.

\frac{13}{36}

36

13

Done
