Question

add.
\\(\frac{3}{10} + \frac{3}{4}\\)
write your answer as a fraction in simples

Explanation:

Step1: Find a common denominator

The denominators are 10 and 4. The least common multiple of 10 and 4 is 20. So we rewrite the fractions with denominator 20:
$\frac{3}{10} = \frac{3\times2}{10\times2} = \frac{6}{20}$
$\frac{3}{4} = \frac{3\times5}{4\times5} = \frac{15}{20}$

Step2: Add the numerators

Now add the numerators of the equivalent fractions:
$\frac{6}{20} + \frac{15}{20} = \frac{6 + 15}{20} = \frac{21}{20}$

Answer:

$\frac{21}{20}$
