There would be a ratio of of 3/5 boys to girls. 3/5 of 200 is 120
I feel like that's irrelevant because those numbers don't add up.
Take 1 unit so 1/8 then factor it into 200.
you get 25
25*3 is 75.
75 is 37.5% of 200

The percentage of male students is 37.5%

- There for every five girls there are three boys.

- That is eight students per.

- I took two hundred and divided it by eight to get twenty-five.

- I got twenty five, if you take twenty-five times three you get seventy-five & if you take twenty-five times five you get one hundred twenty-five.

- Add those two products and you'll have your two hundred.

- So, take seventy-five over two hundred to get thirty-seven and a half.

- Divide that by one hundred to get the ratio.

- It comes out to 37.5%

  • 60% of the total students voted to be the falcons .

\large\bf{\underline{To \:find }}

Vladimir [108]
In July:
First week:
Number of people went to the local swimming pool =1040
Second week:
110 fewer people went to the pool than in the first week
so,
Number of people went to the local swimming pool =1040-110
=930
Third week:
130 more people went to the pool than in the second week
so,
Number of people went to the local swimming pool =930+130
=1060
Fourth week:
228 fewer people went to the pool than in the third week
so,
Number of people went to the local swimming pool =1060-228
=832
Decrease in number of people over four week= number of people in first week - number of people in fourth week
Decrease in number of people over four week=1040-832
=208
