Question

solve 3/5 + 2/7 + 13/35 ​

Answer 1

Given:

Add 3/5 + 2/7 + 13/35

Explanation:

• First before anything, dont forget to make all the denominators same while you do operations lile addition and subtraction
• Then just add the numerators and make sure to write the answer in the shortest form.

=> Making denominators same:

• Inorder to make all the denominators same, we have to find the LCM of all the denominators.

LCM of 5,7 and 35 is 35.

• Now multiply each of the denominators with the appropriate number to make their denominator 35.
• Make sure to multiply the same number you have done in denominators with the numerators too.

$\frac{3}{5} = \frac{3 \times 7}{5 \times 7} = \frac{21}{35}$

$\frac{2}{7} = \frac{2 \times 5}{7 \times 5} = \frac{10}{35}$

$\frac{13}{35} = \frac{13 \times 1}{35 \times 1} = \frac{13}{35}$

Now, adding all the fractions:

$\frac{21}{35} + \frac{10}{35} + \frac{13}{35} = \frac{(13 + 10 + 21)}{35} = \frac{44}{35}$
