I’m assuming the information you’ve given is for a picture. However, the picture isn’t showing.
We can use ratios to find the answer to this.
Set up the ratio.
3/4 / 18/7 = x / 1
Multiply both sides by 1
3/4 / 18/7 = x
Inverse 18/7 to 7/18 so we can multiply.
3/4 * 7/18 = x
Multiply.
21/72 = x
Simplify7/24 = x
Therefore, 7/24 cups of oats is used per pound.
1/5 the slop is the rise over run
It would be: 11/18 - 1/6
= 11 - 3 / 18
= 8/18
= 4/9
In short, Your Answer would be Option D
Hope this helps!
