Answer 1 · 2018-03-05T01:41:16

69/10

Explanation:

$\frac{9}{2} + \frac{12}{5}$ $9/2+12/5$

$\frac{45}{15} + \frac{24}{10} = \frac{69}{10}$ $45/15+24/10=69/10$

Answer 2 · 2018-03-05T01:41:53

$6 \frac{9}{10}$ $6 9/10$

Explanation:

Find a common denominator for 2 and 5, which is 10. Then adjust the fractions accordingly. $4 \frac{1}{2} + 2 \frac{2}{5} = 4 \frac{5}{10} + 2 \frac{4}{10} = 6 \frac{9}{10}$ $4 1/2 +2 2/5 = 4 5/10 +2 4/10 = 6 9/10$

Answer 3 · 2018-03-05T01:42:36

$6 \frac{9}{10}$ $6 9/10$

Explanation:

Method 1

$4 \frac{1}{2} + 2 \frac{2}{5}$ $4 1/2+2 2/5$

$= 4 + \frac{1}{2} + 2 + \frac{2}{5}$ $=4+1/2+2+2/5$

$= 6 + \frac{1 \cdot 5 + 2 \cdot 2}{2 \cdot 5}$ $=6+(1*5+2*2)/(2*5)$

$= 6 + \frac{9}{10}$ $=6+9/10$

$= 6 \frac{9}{10}$ $=6 9/10$

Method 2:

$4 \frac{1}{2} + 2 \frac{2}{5}$ $4 1/2+2 2/5$

$= \frac{9}{2} + \frac{12}{5}$ $=9/2+12/5$

$= \frac{9 \cdot 5 + 12 \cdot 2}{2 \cdot 5}$ $=(9*5+12*2)/(2*5)$

$= \frac{69}{10}$ $=69/10$

$= 6 \frac{9}{10}$ $=6 9/10$
