Separate 252 into two parts using the ratio 2 : 5

So we'd do this like

To separate 252 we will first 

Add 5 and 2(the ratio numbers)  and then if we want to find 2 then we will do it like this 2/7 of 252 !we are dividing it by 7 snd multiplying by 252 becoz we want 2part of 7 of 252!And in the same way we will take out of 5 also !So we sould do it like this

2+5=7

Therefore

2/7 x 252 (now we will cut 7 and 252 and then multiply the answer by 2)

=2 x 36 

=72

Now we will use the same formula for 5

5/7 x 252 

=5 x 36 

=180 

So our numbers which add up to 252 are 72 and 180  (proof:72 + 180 - 252)

So the two parts of 252 are 72 and 180

There are 7 (= 2 + 5) segments in total, so 1 segment = 252/7 = 36.

This means 2 segments = 2*36 = 72 and 5 segments = 5*36 = 180.

So the two parts are 72 and 180.

Check:  72/180 = 2*36/(5*36) = 2/5,  and 72+180 = 252.

oh!im sorry for posting the answer again!i have just seen that Alan has answered this question becoz i was making mine till the time and so couldnt check that he has answered!But i hope no one minds becoz i too have helped !
