Answer: 3/7
Why?
Reorganize the equation 3x-7y=28 you get
Y=3/7x-4
Because y=mx+b and m=the slope this shows that the slope is 3/7
Hope this helps :D
1/3 of 1/4 is the same as 2/6 of 2/8
(easier for me this way)
2/6 is 0.33
2/8 is 0.25 so you are in essence finding roughly 0.8333
that would be equal to the diagram at the bottom right
The other question is (i believe) 1/5 of 5/6
1/5 is 0.2, 5/6 is 0.833
another way to do it is to divide 833 by 5 is 166.6 so it would be 0.166
that would (i think) be the top right
