Answer:
y=1.125x
Step-by-step explanation:
9/8 is the ratio
so, I would do 9/8 which is 1.125. so, one euro is worth 1.125 dollar
y(dollars)=1.125x(euros)
TEST
27 dollars=1.125 • 24
done
What you want to do is find the greatest common denominator, so for now put the 17 to the side and focus on the 1/4 and 7/8, we can find the GCD (greatest common denominator) by multiplying 1/4 • 8/8 = 8/32 And then multiplying 7/8 • 4/4 = 28/ 32 So here we have remaining 17 & 8/32 cups PLUS 28/32 cups, you can add the numerators straight across and keeps the denominators the same, which says that she uses 18 & 4/32
Simplified version: 18 & 1/8
The answer is 5. The biggest number - the smallest number (18-13=5)
7 different ways is the answer
