Quinn's mom went to the same middle school that Quinn is now attending. The current student population is 817 students. Since Quinn's mom attended, the school has experienced a
57% increase in population. About how many students were enrolled at the school when Quinn's mom attended?

Answers

Answer:

520

Step-by-step explanation:

Past number of pupils: p

Increase of 57% = 1.57

Present number of pupils = 817

p x 1.57 = 817

p = 817 divided by 1.57 = 520.382

rounded to the nearest whole number = 520 (this is why the question says "about" how many...)

57 x 817 = 46569

46569 divided by 100 = 465.69

817-465.69 = 351.31

Answer : 351

Explanation : 57 times 817 equals to 46569 and then you divided by 100 . Then it equals to 465.69 . To find out the how many more students were enrolled you have to subtract 465.69 from 817 and then you get 351.31 which you round to 351 .

wait a min i searched it up and it '=' to decimals. What does this equal to in fractions?

Answers

Answer: 12/55
Because: I did the math

Answer:

15/11 or 1 and 4/11

Step-by-step explanation:

I like to use the trick "Keep it, change it, flip it." for division of fractons.  So keep 6/11 how it is, change the division sign to multiplication, and change 2/5 to 5/2, (Basically just flipping it.) Now multiply like how you would multiply fractions.  Multiply numerators , (6 and now 5) by eahother and denominators, (11 and now 2,)  by eachother as well.  You get 30/22, which simplifies to 15/11.  The mixed number version is 1 and 4/11 if you need that instead.    

I hope this helps so that you don't have to search it up again!
