If 48/64 are both divided by 8 you would get 6/8! these can still be reduced to 3/4, So FALSE!
Answer:
(a)
and 
Step-by-step explanation:
Required
Which of a to d has no solution
(a)
and 
We have: 
Sole for m



Divide by 6

So, we have:
and 
implies that: m = -6,-7,-8,-9.....
implies that m = -3,-2,-1,0.....
<em>Hence, there is no solution</em>
Take any 2 points the answer will be the same.
For point 2 and 3 : (-4)-(2)/(0)-(-1) = -6
the answer is -6
So first I hope this helps! But from what I’ve learned in school is that a unit rate pretty much just mean *1... so in words the answers would be 1/6 and hour for every 2/23 miles
