Question

Order these numbers from least to greatest.186-145, 12- 12.10'7'

Answer 1

Answer:

$-\frac{5}{21}$

Explanation:

Given the below;

$-\frac{2}{3}+\frac{3}{7}$

To add the above, the 1st step is to determine the LCM of 3 and 7.

Since 3 and 7 are prime numbers, therefore their LCM will be their product ( 3 x 7 = 21). So we'll have;

$-\frac{2}{3}+\frac{3}{7}=\frac{-14+9}{21}=-\frac{5}{21}$
