Can someone please explain this to me in detail? Thank you! To make 4 3/5 cakes, 2/3 pounds of flour is needed. How much flour is needed to make one cake?

Answer 1

suppose you know how much you need to make 3 cakes. To make one cake, you just divide by 3, right?

So here, just divide by 4 3/5.

(2/3)/(4 3/5)
= (2/3)/(23/5)
= 2/3 * 5/23
= 10/69

All fractions work the same way.

Answer 2

Thank you Steven! I did this problem all kinds of ways,but the answer is 0.80 pounds. I'm trying to figure out how the got that. I was up study late,so maybe I missed something simple.

Answer 3

something is messed up.

I suspect a typo. In particular, I think 4.6 cakes will take a lot more than 3/5 lb of flour, unless they are very small cakes.

Hmmm. 2/3 lb is about 3/5 cup. I know I can't make 4 cakes with that much flour!
