4 : 7 = n1 : n2+60





n1 = 4 * (60 / (7-4)) n2 = 7 * (60 / (7-4))





n1 = 4 * (60 / 3) n2 = 7 * (60 / 3)





80
4 * 20
140
7 * 20

    oopps... the first one is a mess... let me correct that... :D

    4 : 7 = n1 : n2+60

    n1 = 4 * (60 / (7-4))
    n2 = 7 * (60 / (7-4))

    n1 = 4 * (60 / 3)
    n2 = 7 * (60 / 3)

    80 = 4 * 20
    140 = 7 * 20

Ann has 80 pesos and Rosa Has 140 pesos. Calculated by taking the 4 to 7 ratio and keep multiplying until you reach the 60 pesos difference which is 4X20=80 and 7X20=140. 140 minus 80 = 60.

Solving ratio problems


There is a problem with the numbers you quote.

20 x 2/3 = 13.3 boys

You can't have 0.3 of a boy. So round that off to 13 boys. Girls are

20 - 13 = 7 in number. This is the nearest sensible answer.

The average age of 3 girls is 20 years and their ages are in the ratio 3:5:7.The age of the eldest girl is:


The average is 20, it means the total is 60. The sum of ratio is 15 (3+5+7)
Therefore the age of a girl is calculated by multiplying the respective ration with total and dividing by sum of ratio
Age of Eldest girl = 7 x 60 /15 = 28

Hope it helps! Good Luck!

There are 40 pupils in a class .twenty five of them are boys.what is the ratio of boys to girls?


If there are 40 total students, and 25 are boys, then (40-25) of them are girls, or 15.
That means the ratio of boys to girls is 25 to 15, or 25/15
This can be simplified by dividing by 5, so the ratio is 5/3
