Question

Jordan is mixing water and flour to make tortillas. The number cups of water, w needed for f cups of flour is described by the equation w=0.75f. How many cups of flour are needed to mix with 1 cup of water?

Answer 1

`1(1)/(3)` cups of flour.

Explanation:

Given that:

`w` is the number of cups of water to be mixed with flour for making tortillas.

`f` is the number of cups of flour to be mixed with water for making tortillas.

Relation between
`w` and
`f` is given by the equation:

`w=0.75f`

To find:

Number of cups of flour to be added if number of cups of water to be used is 1.

Solution:

We are given an equation with two variables.

Value of one variable is given and we have to find the value of other variable.

`1=0.75f\\\Rightarrow f = (1)/(0.75)\\\Rightarrow f = 1.33`

Number of cups of flour to be added =
`1(1)/(3)`
