5/12-3/8 In Simplest form can someone please break it down so I can understand how to get the answer..

jeka94

To find 5/12-3/8, you have to find a common denominator. A common denominator of 12 and 8 could be 24. So, you multiply 5/12, both the numerator and the denominator by 2, which gives you 10/24. Then, you multiply 3/8 both by 3 to get the common denominator of 24. 3/8x 3 is 9/24. So, 10/24-9/24 is 1/24 because you only subtract the numerator and keep the denominator the same.

$- 13.8 = \frac{u}{5} - 1.3$

$- 13.8 + 1.3 = \frac{u}{5}$

$- 12.5 = \frac{u}{5}$

$- 12.5 \times 5 = u$

$- 62.5 = u$
