3/4= x/8
3 is to 4 as x is to 8
cross multiply
(3*8)= (4*x)
24= 4x
divide both sides by 4
6= x

3/4= 6/8

Or 4 goes into 8 two times. Multiply 3 by two, which equals 6

Add 6/8 to 5/8:
6/8 + 5/8
=11/8
=1 3/8 mixed number

ANSWER: 6/8 and 1 3/8

Hello!

To convert [tex] \frac{3}{4} [/tex] to a fraction with a denominator of 8, multiply the fraction by [tex] \frac{2}{2} [/tex]; [tex] \frac{2}{2} =1[/tex], so the fraction is equivalent, but would have an increased numerator and denominator.

[tex] \frac{3}{4} * \frac{2}{2} = \frac{6}{8} [/tex]

Your new fraction is [tex] \frac{6}{8} [/tex]. Add it to [tex] \frac{5}{8} [/tex]:

[tex] \frac{6}{8} + \frac{5}{8} = \frac{11}{8} [/tex]

Now we must convert it to a mixed number. To do that, divide 11 by 8.

Answer:
[tex]1 \frac{3}{8} [/tex]
