Answer:

7. 6/8 & 7/8

8. 8/12 & 3/12


Step-by-step explanation:

For number 7, the LCD is 8.

So,
(3)/(4) *
(2)/(2) = (3*2)/(4*2) = 6/8


For number 8, the LCD is 12.

So,

(2/3) = (2/3) * (4/4) = (2*4) / (3*4) = 8/12

(1/4) = (1/4) * (3/3) = (1*3) / (4*3) = 3/12


Hope this helps u!!

If it did, let me know and leave a thanks:))

Hello from MrBillDoesMath!

Answer: #7 ( 6/8 and 7/8)

#8 (8/12 and 3/12)

Discussion:

#7

3/4 and 7/8. The common denominator is 8 so let's multiple numerator and denominator of (3/4) by 2 to get 8in the denominator

(3/4) * (2/2) = (3*2)/(4*2) = 6/8


#8


2/3 and 3/4. Intuitively, multiply the denominators 3 and 4 gives 12. Use that as a denominator.


(2/3) = (2/3) * (4/4) = (2*4)\(3*4) = 8/12


(1/4) = (1/4) * (3/3) = (1*3)/(4*3) = 3/12


Thank you,

MrB
