Answer 2

Answer:

The answer is $1\frac{23}{105}$
Step-by-step explanation:

STEP 1 : Find the LCM

LCM OF 5,7 AND 9 = 315

STEP 2: Make the numerators and denominators equal

$\frac{3}{5} =$  3x63/5x63 = $\frac{189}{315}$

$\frac{2}{7} =$ 2x45/7x45 = $\frac{90}{315}$  

$\frac{3}{9}$ = 3x35/7x45 = $\frac{105}{315}$

STEP 3: Now add all of them

$\frac{189}{315}+ \frac{90}{315} + \frac{105}{315}$ =    $\frac{384}{315}$ = $\frac{128}{105}$

STEP 4: Convert the answer to a mixed fraction
$\frac{128}{105} = 1\frac{23}{105}$

Hope this helps!
