Question

How do you express .67 as a percent?

Answer 1

See a solution process below:

Explanation:

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

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

`0.67 = 67/100 = 67%`

Answer 2

When you have a decimal and you want to turn it into percentage, you just take the decimal and multiply it by `100`

`0.67 xx 100`= 67

Then just add the percentage sign, which is this %

The answer is `67%`

Answer 3

`67/100color(white)("d") ->color(white)("d")67%`

Explanation:

`color(blue)("Answering the question")`
0.67 is the same as `0+6/10+7/100`

Percentage is just a fraction but a special one where the denominator (bottom number) is fixed at 100.

So we have `("some number")/100` and this is what we need to end up with.

Multiply by 1 and you do not change the value. However, 1 comes in many forms.

`color(green)([6/10color(red)(xx1)]+[7/100])`

`color(green)([6/10color(red)(xx10/10)]+[7/100])`

`color(green)([(6color(red)(xx10))/(10color(red)(xx10))]+[7/100])`

`color(green)([60/100]+[7/100] = (60+7)/100=67/100)`

Given that we have `67/100 ->("Numerator")/("Denominator")->("count")/("size indicator")`

So we have `color(purple)(" count of size indicator")`
`color(purple)(color(white)("dddddddddddd")darr color(white)("ddd.")darr color(white)("dddd.d")darr`
`color(white)("dddddddddddd") 67 color(white)("dd.d")xxcolor(white)("ddddd")1/100`

But `1/100` is the same sort of thing as `%`

So we have:
`67xx1/100color(white)("ddd")->color(white)("ddd")67xx%color(white)("ddd")->color(white)("ddd")67%`

Adding fractions that have the same 'size indicators' does not change the 'size indicator'. Just the counts.

This is a bit like 2 inches + 3 inches = 5 inches does not change the 'size indicator' (unit of measurement of inches)
