$1 \frac{29}{70}$ $1frac(29)(70)$

first find the common denominator in this case the LCM is 70.

Multiply each fraction by the fraction that =1 which makes the denominator 70

$\frac{7}{10} \cdot \frac{7}{7} = \frac{49}{70}$ $7/10*7/7=49/70$ and $\frac{5}{7} \cdot \frac{10}{10} = \frac{50}{70}$ $5/7*10/10=50/70$

now add these and put into mixed number form

$\frac{49}{70} + \frac{50}{70} = \frac{99}{70} = 1 \frac{29}{70}$ $49/70+50/70=99/70=1frac(29)(70)$
