Question

One pound of grapes costs $1.55. WWhich equation correctly shows a pair of equivalent ratios that can be used to find the cost of 3.5 pounds of grapes?

Answer 1

Given:

Given that, one pound of grapes cost is $\ 1.55$.

To find:

We need to find the equation which shows a pair of equivalent ratios that can be used to find the cost of $3.5$ pounds of grapes.

Solution:

Let the cost of $3.5$ pounds of grapes is $x$.

So, the cost of 1 pound will become $=\frac{x}{3.5}$.

According to the question, one pound of grapes cost is $\ 1.55$.

So, $\frac{x}{3.5}=1.55$

$\Rightarrow \frac{x}{3.5}=\frac{1.55}{1}$

The above equation is the equation of equivalent ratios. With the help of this ratio, we can find the cost of $3.5$ pounds of grapes.

Therefore, the equation of equivalent ratios is $\frac{x}{3.5}=\frac{1.55}{1}$.
