What is #15/16 - 7/8#?

Answer 1

See explanation...

Alright, to add of subtract two fractions, we have to make sure that they have the same denominator. To do this, lets multiply the #7/8# by #2/2# so that they both have the same denominator.

#=15/16-7/8#

#=15/16-7/8*2/2#

#=15/16-14/16#

Now we can just solve

#=(15-14)/16#

#=1/16#

To find the difference between ( \frac{15}{16} ) and ( \frac{7}{8} ), you need to have a common denominator, which in this case is 16. Then you can subtract the numerators while keeping the denominator the same.

( \frac{15}{16} - \frac{7}{8} = \frac{15}{16} - \frac{14}{16} = \frac{1}{16} )
