Answer 3

To add these fractions, you need to have a common denominator. In this case, the common denominator is 78. Then, you can add the numerators and keep the common denominator.

$\frac{19}{78} + \frac{53}{78} + \frac{37}{78} + \frac{21}{78}$

Combine the numerators:

$= \frac{19 + 53 + 37 + 21}{78}$

$= \frac{130}{78}$

Now, you can simplify the fraction. The greatest common divisor of 130 and 78 is 26.

$= \frac{130 ÷ 26}{78 ÷ 26}$

$= \frac{5}{3}$

So, $\frac{19}{78} + \frac{53}{78} + \frac{37}{78} + \frac{21}{78}$ is equal to $\frac{5}{3}$.
