Given the statement:
3/5 of the students in a classroom are girls.
Determine how many students are there in total if 10 are boys.
Solution:
In order to determine how many students are there in total, we must first equate 10 as 2/5 which when combine to 3/5 will equal to the whole class. Now we simply need to divide 10 by 2/5. Note that when dividing a fraction, we instead take the reciprocal of that fraction, and then multiply it with the whole number. In our case, we will multiply 10 by 5/2 which is the reciprocal of 2/5.
= 10/ 2/5
= (10)(5/2)
= 50/2
= 25
Final answer:
There are 25 students in the class.
