Laura is baking a cake. The recipe says that she has to mix 64 grams of chocolate powder to the flour. Laura knows that 1 cup of that particular chocolate powder has a mass of 128 grams. She added of a cup of chocolate powder to the flour. Should Laura add more chocolate powder to make the exact recipe, or did she go over and by what amount?
She went over by of a cup
She needs to add of a cup
She needs to add of a cup
She went over by of a cup
Mari i cant see the pics!pls can u do something about this because or else i wouldnt be able to help you!
Then whatever they r i just cant see them , the main bits which are showing the amount or numbers!
OK....
1 cup has 128 grams
So......1/2 of a cup must have half of that = 64 grams
If she used 2/3 of a cup and only need 1/2 of a cup, what would be the correct answer???
Can you do this one??? (You won't learn anything if I just give you the answers.....)
I don't think we need any pics, rosala !!!!
Read it again, and see if you know how to find the answer......
Wait a sec, guys......
She needed 1/2 of a cup and she used 2/3 of a cup.........ask yourselves the question, first....did she go over??? How would I find out???
(We don't need any pics !!!)
OK......she needed only 1/2 of a cup......but she used 2/3 of a cup.....is 2/3 larger or smaller than 1/2???
What's the answer??? (rosala....you were close to the answer, but you made a small mistake...)
So , i know menatlly that 2/3 is more than 1/2 of a cup but for a proof lets check
1*3/2*3= 3/6
2*2/3*2 = 4/6
so 4/6 or 2/3 is greater!
OK rosala.......how much did she go over if she used 4/6 of a cup and only needed 1/2 (or 3/6) of a cup ????
....And you did it all with no help from any "pictures," either !!!!
Pretty easy, once you saw it, huh???
Very good !!!!
CPhill, I think the problem was that some of the fractions mari used are displayed as pictures for whatever reason.
I'm having this same problem. This is what the question looks like to me:
I'm not seeing any pics, ND........!!!!!
Maybe there's something wrong with MY computer !!!!
Sorry....I ddidn't realize it was displaying like that for you guys....apologies
