Question

How do I simplify 3/8-6/7

Answer 1

Answer:

$\frac{-27}{56}$

Step-by-step explanation:

First, we will subtract.

[] Let's find common denominators.

8 -> 8, 16, 24, 32, 40, 48, 56, 64, 72, 80

7 -> 7, 14, 21, 28, 35, 42, 49, 56

$\frac{3}{8}=\frac{3*7}{8*7} =\frac{21}{56}$

$\frac{6}{7} =\frac{6*8}{7*8} =\frac{48}{56}$

(multiplying by these numbers does not affect them because, for example, $\frac{8}{8}=1$)

[] Subtract across the numerators, the denominator stays the same

$\frac{21}{56} -\frac{48}{56} =\frac{-27}{56}$

[] Simplify

-> To simplify, we can find common factors

For 27: 1, 3, 9, and 27

For 56: 1, 2, 4, 7, 8, 14, 28, and 56

-> $\frac{-27}{56}$ does not have any common factors besides one, so it is fully simplified
