4/x = 36/100 =

1.)Mrs. Neruda has 80 math student last year. This year she has 100 math students. What percent shows the ratio between the number of students last year and the number of students this year?

#2)A can of soda contains 39 grams of carbohydrates. This is 13% of the value recommended for a daily diet of 2,000 calories. How many grams of carbohydrates are allowed in this daily diet?

#3)4 36

- = - =

x 100

For the first question, 100=80x, x being the percentage decimal. x=1.25, so the percent is 125%.

For the second one, 39=0.13x. x=300, so you are allowed 300 grams of carbs.

I can't read the third problem.

Hope that helps!

OK - there are a few ways you can do this. One way is to cross multiply 4*100=36x. Then divide both sides by 36 to get x. Another way would be to see that 4 was multiplied by 9 to get to 36. So, what would be 100 divided by 9? x=11.1 repeating.
