90% of 130 is 117 because 10% is 13 and 13x9 is 117 so that is part a. 130-117 is 13 so that is part b. And part c is correct because 100%-90%=10%. I hope this is helpful.

An after-school care facility tries to maintain a 2-to-1 ratio of children to adults. If the facility hired five adults, what is
astra-53 [7]

Answer:

10 children

Step-by-step explanation:

If we have a ratio of 2:1 children:adults, then we can find out how many children max can enroll if there are 5 adults.

Our original ratio was 2:1 and now it's x:5, assuming x is the number of children enrolled. We multiply 1 by 5 to get to 5, so we need to multiply 2 by 5 to get the total number of chlidren.

2 × 5 = 10

Hope this helped!

There are 285 seventh-graders at Greg's school.
Varvara68 [4.7K]

Answer:

124 boys and 161 girls

Step-by-step explanation:

There are 285 students total. Divide 285 by 2, you get 142.5. Since you can't have half a student, lets round it up to 143. Now, there are 19 more girls than guys, so you would subtract 19 from 143. When you do that, (143-19) you get 124. Then you take 285 and subtract 124. You get 161.

Hope this is correct!
