Will ate 4 out of the 5 cookies on the plate. what percent of the cookies did he eat

To solve this, we turn the fraction 4/5 to x/100, and x is our percent.

We know 5 * 20 = 100, so 4 * 20 = x. x = 80

So, 4/5 = 80/100

Will ate 80% of the cookies.

You can convert this question into a fraction: 4/5 where 4 = the cookies Will ate and 5= the cookies that were on the plate.

Simple You just convert 4/5 into a decimal, which is .8 or 80%

Complicated If you convert this into a percentage, you can either use a proportion: 4/5=x/100 and then cross multiply, which gives you 5x=400. After that, we divide both sides by 5, thus getting rid of the 5 next to the x, and you're left with x=80. So, 4/5 is equal to 80%.

Hope this helped. :)
