1/5+1/7+3/21 the answer is
inessss [21]

Answer:

<h2>17/35</h2>

Step-by-step explanation:

We need to get all the fractions with a common denominator before we can solve the problem.

The only fractions that have a common multiple are 1/7 and 3/21, so we'll add these first and then add 1/5.

1/7 = 3/21

Add

\frac{3}{21} + \frac{3}{21} =\frac{6}{21}

6/21 = 30/105

1/5 = 21/105

\frac{30}{105} + \frac{21}{105} = \frac{51}{105}

Simplify

\frac{51}{105} / \frac{3}{3} =\frac{17}{35}

<h3>ANSWER: 17/35</h3>

I'm always happy to help :)
