If you ate 1/5 of the desert served at
dinner, what percent of the food did you
eat?

20%

Step-by-step explanation:

so to become a percentage, you should multiply by 100% (which is basically 100/100 but don't multiply the bottom instead you write a percent sign)

So 1/5*100/100 without multiplying the bottom is:

100/5%

100 divided by 5 is 20. There you go! And you can use a calculator if that is easier for you. All you do is 1/5 which is .20 and your answer is 20%! Hope this helps!

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !

391.6 is the correct answer
