Answer:

\displaystyle y=\frac{7}{4}.x

Step-by-step explanation:

<u>Proportional Relationship</u>

It's the type of relationships between two variables where their ratios are equivalent.

In a proportional relationship, one variable is always a constant value by the other. That constant is known as the <em>constant of proportionality</em>.

A proportional relationship between the variables x and y is written as:

y=k.x

For this problem, y represents the cups of water needed for making x loaves of French bread.

We know Marley used y=7 cups of water to make x=4 loaves of French bread. Substituting into the equation:

7=k.4

Solving for k:

\displaystyle k=\frac{7}{4}

The equation to model the problem is:

\mathbf{\displaystyle y=\frac{7}{4}.x}

If 2/5 divided by blank = 4/5 what is blank
Helen [10]
2/5 ÷ x = 4/5
multiply both sides by x to get it out of the denominator.
2/5 = 4/5x
now divide each side by 4/5 to get x by itself.
2/5 ÷ 4/5 = x
divide fractions by multiplying the reciprocal of the divisor.
2/5x × 5/4 = x
10/20 = x
1/2 = x

So 2/5 divided by 1/2 =4/5
