What percent of $5 is $3.75?

nataly862011 [7]

Answer:

75%

Step-by-step explanation:

We can use the formula $\frac{is}{of}=\frac{percent}{100}$

"of" is 5
"is" is 3.75
We will denote "percent" as x since that is what we are solving for

Now we just need to plug in the known values and solve for x

$\frac{3.75}{5}=\frac{x}{100}$
Cross multiplying we get (5)(x) = (3.75)(100)
Then simplifying we get 5x = 375
Dividing by 5 we get x = 75%

$3.75 is 75% of $5
