So 3 and 1/4 is equal to 4/4+4/4+4/4+1/4=13/4
so she put in 3 and 1/9 or 9/9+9/9+9/9+1/9 or 28/9
28/9+x=13/4
13/4-28/9=x
so we convert so that the bottom numbers are the same
a short cut is 3 and 1/4+x=3 and 1/9
3 1/9+x=3 1/4
subtract 3 from both sides
1/9+x=1/4
subtract 1/4 from both sides
x=1/4-1/9
convert bottom number to same thing
1/9=4/36
1/4=9/36
x=9/36-4/36
x=5/36
5/36 cups
Answer:
we get 
Step-by-step explanation:
We are given: 
We need to find 
Note: Since question is not clear, I am assuming that we need to find
Solving:
We know that 
Using formula and simplifying
So, we get
Answer: 4
Step-by-step explanation: We can rewrite this as 5 1/4 - 1 1/4 which equals 4.
0.6 > (or equal too) 2.4 - n
And n = any number less than or equal too 1.8
