Its mostly algebra- fractions decimals percents proportions equations expression ratios and etc
Look for examples and context. For example, a recipe will always talk about fractions of cups, tablespoons, etc. If you're talking about the chance of rain, you would express that as a percentage.
They can all look like fractions.
A ruler
3/8
1/2 cups.
3/10
list of few things that look like a cube?
Four over three. 4/3
If you're looking at a list, I can't help you pick the correct answer from it as long as you refuse to share it. Look for fractions in the form of (any multiple of 5)/(the same multiple of 6) .
Do 7/10 which equals 0.7 then times that by 100 which will give you 70. So heres how it should look:7/10=.7.7*100= 7070=70%Simple right? I hope this helped explain how you turn fractions into percents!
300*.83=249. Look up how percents work.
