Question

Convert the following rational numbers to rational numbers having same denominator.
$\frac{-3}{4}, \frac{2}{3}, \frac{5}{6}, \frac{7}{-8}$

✓

Answer

For same/common denominators, LCM of 4, 3, 6, 8 is 24,
$\frac{-3 \times 6}{4 \times 6}, \frac{2 \times 8}{3 \times 8}, \frac{5 \times 4}{6 \times 4}, \frac{7 \times 3}{(-8) \times 3}$
So, $\frac{-18}{24}, \frac{16}{24}, \frac{20}{24}, \frac{-21}{24}$
