of the 50 members of mathematics club 30% are the are also member of science club how many members of the club are also members of science club

Answer:

15 members

Step-by-step explanation:

When we are using percentages, what we are really saying is that the percentage is a fraction of 100. “Percent” means per hundred, and so 50% is the same as saying 50/100 or 5/10 in fraction form.

So, since our denominator in 30/50 is 50, we could adjust the fraction to make the denominator 100. To do that, we divide 100 by the denominator:

100 ÷ 50 = 2

Once we have that, we can multiple both the numerator and denominator by this multiple:

30 x 2=60

50 x 2=100

Now we can see that our fraction is 60/100, which means that 30/50 as a percentage is 60%.

We can also work this out in a simpler way by first converting the fraction 30/50 to a decimal. To do that, we simply divide the numerator by the denominator:

30/50 = 0.6

Once we have the answer to that division, we can multiply the answer by 100 to make it a percentage:

0.6 x 100 = 60%
