Question

In a school 5/9 of the students are boys and the number of girls is 800. find the number of boys.​

Answer 1

Answer:

Step-by-step explanation:

1000

Total number of boys = 1000

Step-by-step explanation:

Let the total number of students be 'x' . Then,

No. of boys = 5/9 of x = 5x/9

Therefore , no. of girls = x - 5x/9

= 4x/9

But the no. of girls = 800 (given)

Therefore,

4x/9 = 800

x = 800 × 9/4

x = 1800

Thus, total no. of students = 1800.

Hence, total no. of boys = 5 × 1800/9 = 1000

So, total number of boys = 1000

Answer 2

Answer:-

given;-

•  5/9 of total students are boys, hence the remaining ratio will be number of girls =

$\sf{1-\dfrac{5}{9} = \dfrac{4}{9}}$

Total number of girls = 800

Total number of girls = ↓

$\sf{Total\:no:of\:boys\:and\:girls\:x\:\dfrac{4}{9} = 800}$

$\sf{Total\:strength = 800\:x\:\dfrac{9}{4} = 1,800}$

$\boxed{\bf{Total\:no: of\:boys = 1,800\:x\:\dfrac{5}{9} = 1, 000 }}$

$\boxed{\bf{Total\:no: of\:girls = 1,800\:x\:\dfrac{4}{9} = 800 }}$
