plz say fast it's very urgent..

Answer 1

Answer:

RATIO = 8:5 ::: GIRLS : BOYS

LET GIRLS NUMBER =8X AND BOYS = 5X

GIVEN BOYS = 175 , SO 5X = 175 , SO X = 35 ..

GIRLS = 8X = 8 . 35 = 280..

TOTAL = 280 + 175 = 455

Step-by-step explanation:

Answer 2

Given:

• The ratio of the girls to the number of boys in the school is 8:5
• The number of boys is 175.

To be found:

The total number of students in the school.

So,

Let the number of girls be 8x

And let the number of boys be 5x

So, number of boys = 175 = 5x

⇒ 5x = 175

⇒ x = 175 ÷ 5

[∴ Taking 5 to RHS]

⇒ x = 35

So, we got the value of x = 35

Now, we can find the number of girls.

= 8x

= 8 × 35

= 280

Now,

We got

Number of boys = 175

And the number of girls = 280

Then

Total number of students

= Number of boys + number of girls

= 175 + 280

= 455

Hence,

There are 455 students in the school.
