a certain recipe asks for 8/9 cup of granola. how much is needed to make 7/9 of a recipe . To make 7/9 of a recipe ___ cup of granola is needed is my answer 4/5 can some one check see if it correct doing test
@agent0smith ...can you help. I don't know if I am even doing this correctly.....If it takes 8/9 for the entire recipe and you are making 7/9...would you just subtract 2/9 from 8/9 equaling 6/9 equaling 2/3 ? Or am I way off on how to do this problem ???
You need to multiply them.
multiply what ? 2/9 * 8/9 ? what needs to be multiplied ?
oh.....I was way off.....thx for getting me on track
If you want to make twice the recipe, you'd have to double the 8/9 right? ie 2*8/9. If you want only 7/9 of the recipe, 7/9*8/9
I tried that earlier by setting the problem up as a proportion...I thought I was doing it wrong
Thats the product when you multiply...so yes....56/81
so that the answer 56/81
I think so.....according to agent0smith....and this person knows math.
