Answer:

1 7/12

Step-by-step explanation:

2 Find the Least Common Denominator (LCD) of \frac{5}{6},\frac{3}{4}

. In other words, find the Least Common Multiple (LCM) of 6,46,4.

LCD = 1212

3 Make the denominators the same as the LCD.

\frac{5\times 2}{6\times 2}+\frac{3\times 3}{4\times 3}

6×2

5×2

4×3

3×3

4 Simplify. Denominators are now the same.

\frac{10}{12}+\frac{9}{12}

5 Join the denominators.

\frac{10+9}{12}

10+9

6 Simplify.

\frac{19}{12}

7 Convert to mixed fraction.

1\frac{7}{12}1
