1.	if the ratio of boys and girls of a school is 4 ratio 5 and there is a increment of boys by 30% and increasement in girls by 40% find the new ratio of boys to girls
Answer» ANSWER: Step-by-step explanation: There is an important DIFFERENCE between the way counts are viewed in ratio to that in fractions. The ratio of boys : GIRLS →4:5 so you have 4 boys and 5 girls making the whole count 4+5=9 in its simplest form. So to change the ratio proportion into fraction proportion we have: boys →4/9 of the whole. girls →5/9of the whole. It is given that the whole is 3321 therefore the count of boys is: 4/9×3321=1476

ANSWER:

Step-by-step explanation:

There is an important DIFFERENCE between the way counts are viewed in ratio to that in fractions.

The ratio of boys : GIRLS →4:5

so you have 4 boys and 5 girls making the whole count

4+5=9

in its simplest form.

So to change the ratio proportion into fraction proportion we have:

boys →4/9 of the whole.

girls →5/9of the whole.

It is given that the whole is 3321 therefore the count of boys is:

4/9×3321=1476
