Question

3/8th of the students of grade 7 were boys. If there were 60 boys in grade 7, how many students will be there in grade 7?

Answer 1

If 3/8th of the students of grade 7 were boys and there were 60 boys in grade 7, then students in grade 7 will be 160.

Step-by-step explanation:

Let the total no. of students in grade 7 be “x”.

We are given that, 3/8th of the total students of grade 7 are boys and there were 60 boys in grade 7, therefore we can write the equation as,

(3/8) * x = 60

⇒ x = [60 * 8] / 3  

⇒ x = 480/3

⇒ x = 160

Thus, there are a total of 160 students in grade 7.

Answer 2

Step-by-step explanation:

.

${\tt{Boys \:in\:\: fraction={\dfrac{3}{8}}}}$

${\tt{Boys\:in \: \:numbers=60}}$

${\tt{So,\: Let\:the\: number\:of\: students\:be\:x.\\\\Therefore,}}$

${\sf{\dfrac{3x}{8}}=60}$

${\tt{x=}{\dfrac{8×{\cancel{60}}}{\cancel{3}}}=160}$

So the total number of students are 160.
