Step by step
The question
Question: write 6/8 as a percent.
1 Simplify first
6 and 8 can both be divided by 2.
Smaller numbers are easier.
So it is 3/4.
2 Make the bottom 100
Percent means out of 100.
So we want a bottom of 100.
4 times 25 is 100.
We multiply the top and the bottom by 25.
25/25 is 1, so the value stays the same.
3 times 25 is 75.
So we get 75/100.
Careful!
As a decimal, 6/8 is 0.75.
But 0.75% means 0.75 out of 100: far too small.
3 Write the percent
75 out of 100 is 75%.
4 Check
Let's check: go back.
75% is 75/100.
Divide the top and the bottom by 25.
We get 3/4, the same as 6/8.
So the answer is right!
Let's look back.
First: simplify first.
Then: make the bottom 100.
Then: write the percent.
Last: check.
