Question

the ratio of boys to the girls is 5 is to 3 if the number of girls is 300 what is the number of boys​

Answer 1

Answer:

3/5of300=3×60=180 equal to nu. of girls

So,boys =total students - nu. of girls

=300–180 = 120

Alternative method ,

Let total students be 1

Nu. of girls =3/4(given)

So ,nu. of boys= 1(total students)–3/5(nu. of girls)=1–3/5=2/5

Then,nu.of boys=2/5 of total students

=2/5×300 = 120

Answer 2

Let the number of boys be x

Explanation:

5/3=x/300

5×300 = 3×x

1500 = 3x

X = 1500/3

X = 500
