Question

WILL FAN IF HELP
Marcus spent 10 hours doing his homework last week. This week he spent 11 hours doing homework. He says that he spent 110% more time doing homework this week. Is he correct? Show your work to justify your decision.

Answer 1

yes

Answer 2

if he spent ten hours last week then the 10 hours is the max amount he has to pass so in fraction wise he has x/10 (a number over ten) from last week if he worked 11 hours this week then it would turn out with 11/10 (eleven over ten) witch means he has already passed the 100% he needed and with 1/10 left you just need 9 more so the equation to do that would be 11 divided by 10 equaling 1.1 then to turn a decimal into a percentage move the dot 2 spaces to the right making it 110%

Answer 3

OK, so if you have something that is a percentage of something else, do you know how to set that up as a formula? understand percentages as completely as you think. You can have more than 100%. For example, if I sell something for 3 times as much as it costs, have 200% profit.If you solve any of these:

10×110%=?
10×?%=11
?×110%=11

And you get the original, it is true.
