Answer 2

Answer:

The greatest rational number is 3/5.

Step-by-step explanation:

The given fractions are :

$\frac{3}{5}$, $\frac{-7}{10}$, $\frac{8}{15}$, $\frac{-19}{30}$

In order to find which fraction is the greatest, we have to make all the denominators of all fractions the same.

So, LCM of 5, 10, 15, 30 = 30

So,

$\frac{3}{5}$ = $\frac{3x6}{5x6}$ = $\frac{18}{30}$

$\frac{-7}{10}$ = $\frac{-7x3}{10x3}$ = $\frac{-21}{30}$

$\frac{8}{15}$ = $\frac{8x2}{15x2}$ = $\frac{16}{30}$

$\frac{-19}{30}$ = $\frac{-19}{30}$

Comparing all these fractions,

18/30, i.e., 3/5 is the greatest rational number.
