Rename 8/9 and 7/18 using the least common denominator.

LCD = 18

8/9 = 16/18

7/18 = 7/18

Step-by-step explanation:

This is the answer because:

1) First, the least common denominator is 18 because 9 x 2 is 18 and 18 x 1 is 18

2) Next, multiply the numerators with the same number you multiplied with the denominator  

8 x 2 = 16  

7 x 1 = 7  

3) Therefore, the answers are:

8/9 = 16/18

7/18 = 7/18  

Hope this helps!

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
