Answer 2

You'll need to add together these two mixed-number quantities and determine whether or not the sum is greater than 4. How would you combine these two numbers?

Answer 3

List out all the given quatities
I'm assuming mean
Eliza - 2 and 1/3 cups or 7/3
Jamie - 1 and 3/4 or 7/4
There's 4 cups of flour avaliable

Answer 4

explain

Answer 5

Next you want to Eliza's and Jamie's flour have the same denominator (bottom #)

YOU CAN'T ADD THEM TOGETHER UNLESS THEY HAVE THE SAME DENOMINATOR

To find the least common denominator, you want to find out the smallest # that 4 and 3 can multiply into

which happens to be 12

Answer 6

i mean like explain how u got the answerr

Answer 7

Haven't gotten the answer yet :P...patience

Answer 8

ok

Answer 9

So, to add them together, both had to have a denominator of 12
7/3
You want to multiply both the numerator and the denominator (top and bottom) by 4 in order to change it to 28/12 (still the same value as 7/3)
7/4
You want to multiply this my 3 (top and bottom)
21/12

Answer 10

now you can add them together
28/12 + 21/12 = 49/12
now you want to simplify this

Together they need 4 and 1/12 cup to make what they want

Since they only have 4 cups

They're 1/12 cup short on flour

Answer 11

So...did ya get all that...or are you completely flabbergasted
