Question

You are tasked to organize a speed dating event for your barangay. Based on previous events, the ratio of male to female attendees is 4:3. For your speed dating event to be successful, you need an equal ratio. 

If 24 males will attend the speed dating event, how many more females do you need to invite from other barangays to ensure an equal ratio of attendees?

Answer 1

Number of males equals $\frac{3}{4}$ of the number of males.

So, if 24 males will attend the speed dating event, the number of males which

will attend the speed dating event is $24*\frac{3}{4}=18.$

Thus, we need to invite $24-18=6$ females to ensure an equal ratio of attendees.
