Answer:

>>   6\frac{5}{18}

Step-by-step explanation:

1) Add the whole numbers first.

5+\frac{5}{6} +\frac{4}{9}

2) Find the Least Common Denominator (LCD) of \frac{5}{6} ,\frac{4}{9} . In other words, find the Least Common Multiple (LCM) of 6,9.

Method 1: By Listing Multiples

1. List the multiples of each number.

Multiples of 6 : 6, 12, 18, ...

Multiples of 9 : 9, 18, ...

2. Find the smallest number that is shared by all rows above. This is the LCM.

LCM = 18

3. Make the denominators the same as the LCD.

5+\frac{5\times 3}{6\times 3}+\frac{4\times 2}{9\times 2}

4. Simplify. Denominators are now the same.

5+\frac{15}{18}+\frac{8}{18}

5.  Join the denominators.

5+\frac{15+8}{18}

6. Simplify.

5+\frac{23}{18}

7. Convert \frac{23}{18} to mixed fraction.

5+1\frac{5}{18}

8. Simplify.

6\frac{5}{18}

Decimal Form: 6.277778

Cheers.
