How do you find the difference never 6/8 - 1/7

Step-by-step explanation:

6/8 - 1/7

And 6/8 = 3/4

The LCM of 7 and 4 = 28

3/4 - 1/7 = {7(3) - 1(4)}/28

= (21 - 4)/28

= 17/28

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
