Question

70%of the students in a school are boys and the number of girls is 504. Find the number of boys in the school

Answer 1

Answer:

1176

Step-by-step explanation:

If 70% of the students in the school are boys, it means that 30% are girls.

Thus, we can use this information to figure out how many people in the school there are, and then we can use that to find the number of boys.

I will use "p" to represent the number of people in the school that there are.

p×0.30=504

Now we have to rearrange and isolate "p", and to do that we have to divide 0.30 out of the equation.

p=504÷0.30

p=1680

Now that we have the number of people in the school, we can multiply 70% by 1680 to find the number of boys in the school.

= 1680×0.70

= 1176

Answer 2

Answer:

see here as 70% are boys out of total students so 30% will be girls

so in 30% there are 504 girls

then in 70% boys there will be 70×504/30

so no of boys are 1176
