Jacob painted 30% of a banner. luis painted an equal amount of the same banner. the rest of the banner remains unpainted. write a fraction to describe the amount of banner that remains unpainted?

Answer = 2/5

Jacob painted 30% of the banner

Luis painted an equal amount, so we can infer that Luis painted 30% of the banner.

Jacob+Luis=

30%+30%=60%

Jacob and Luis painted 60% of the banner. To find the amount of the banner that remains unpainted, simply subtract 60% from 100% ...

100%-60%=40%

Remember that percent means 'out of one hundred', so 40% is the same as 40/100. we can simplify 40/100 to 2/5

2/5 of the banner remains unpainted
