Solve the Fraction Addition: 3/10 + 1/5 + 4/10 Step-by-Step

When we have a fraction addition exercise with more than one fraction, we make sure all the denominators of the fractions are identical.

Let's find the common denominator of the fractions' denominators: $10$ and $5$

The common denominator is $10$.

Now we'll multiply both numerator and denominator of the fraction $\frac{1}{5}$ by $2$ and create a fraction addition exercise where all denominators are $10$:

$\frac{3}{10}+\frac{1\times2}{5\times2}+\frac{4}{10}=\frac{3}{10}+\frac{2}{10}+\frac{4}{10}$

Finally, we'll add all the numerators of the fractions:

$\frac{3}{10}+\frac{2}{10}+\frac{4}{10}=\frac{3+2+4}{10}=\frac{9}{10}$
