On a school trip the ratio of a number of teachers to the number of students is 1 : 15. The ratio of the numbers of male students to the number of female students is 7 : 5. Work out what percentage of all the people of the trip are female students. Give your answer correct to the nearest whole number

( ͡° ͜ʖ ͡° ) copy and   paste it

sorry, i can't understand your question. will later if you describe more clearly!

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
