Question #6fc3c

Answer 1

See a solution process below:

Explanation:

For all of these questions it is important to understand what % or percent represents.

"Percent" or "%" means "out of 100" or "per 100".

Therefore x% can be written as `x/100`.

Question 1: 3 is 1% of what amount.

We can write 1% as `1/100` which also equals `0.01`

Let `n` equal the amount we are looking for. We can write and solve:

`3 = 1/100 xx n`

`color(red)(100) xx 3 = color(red)(100) xx xx 1/100 xx n`

`300 = cancel(color(red)(100)) xx xx 1/color(red)(cancel(color(black)(100))) xx n`

`300 = n`

`n = 300`

`3` is 1% of 300.

Question 2: What percent of 100 is 79?

`79/100 = 79%`

Question 3: What percent of 925 is 37?

Solve `x/100 = 37/925`

Question 4: 247 is 38% of what amount?

Same as question 1 - solve: `247 = 38/100 xx n`

Question 5: What is 78% of 550?

Solve: `n = 78/100 xx 550`
