Question

\frac{2}{5} + \frac{6}{10} + \frac{10}{20} ​

Answer 1

Ответ:

$1 \frac{1}{10}$

Объяснение:

$\frac{2}{5} + \frac{6}{10} + \frac{10}{20} = \frac{8 + 12 + 10}{20} = \frac{22}{20} = 1 \frac{2}{20} = 1 \frac{1}{10}$

Answer 2

To add these fractions together, you first need to find a common denominator. In this case, the common denominator is 20.

Now, you can rewrite each fraction with the common denominator:

• $\frac{2}{5}$ is already in terms of 20, so it remains $\frac{2}{5}$.
• $\frac{6}{10}$ can be converted to $\frac{12}{20}$.
• $\frac{10}{20}$ is already in terms of 20, so it remains $\frac{10}{20}$.

Now, you can add the fractions:

$\frac{2}{5} + \frac{12}{20} + \frac{10}{20}$

To add them together, you add the numerators:

$2 + 12 + 10$

$2 + 12 = 14$

$14 + 10 = 24$

So, the sum is:

$\frac{24}{20}$

Now, you can simplify this fraction. Both the numerator and denominator are divisible by 4:

$\frac{24}{20} = \frac{24 \div 4}{20 \div 4} = \frac{6}{5}$

So, $\frac{2}{5} + \frac{6}{10} + \frac{10}{20} = \frac{6}{5}$.
