Question

Tomas used 3 1/3 cups of flour and now has 1 2/3cups left. Which equation can he use to find f, the number of cups of flour he had to begin with?

f+3 1/3=1 2/3
f-3 1/3=1 2/3
3 1/3f=1 2/3
f/3 1/3=1 2/3

Answer 1

If you don't want to read the other dudes one but ya he did good tho the answer Is b

Answer 2

For this case we have that the variable "f" represents the number of cups of flour that Tomas had initially.

If of that amount Luis used
`3 \frac {1} {3}` of cups of flour, then we have the following expression:

`f-3 \frac {1} {3}`

If Luis has
`1 \frac {2} {3}` cups of flour left, then we have the following equation:

`f-3 \frac {1} {3} = 1 \frac {2} {3}`

Finally, the equation that represents the given situation is:

`f-3 \frac {1} {3} = 1 \frac {2} {3}`
