Example Question #21 : How To Find A Ratio
Phil invites sixty friends from his current school, thirty-five of whom are girls, to his birthday party; he also invites his two female cousins. Phil wants the ratio of girls to boys at the party to be two to one, so he decides to also invite some girls from his old school. How many new girls will he need to invite, assuming he does not invite anyone else?
So far, there are 37 girls - 35 classmates and 2 cousins - and 26 boys - 25 classmates and Mike himself. For the ratio of girls to boys to be 2 to 1, the number of girls must be twice the number of boys, or girls. Mike will need more girls.
Example Question #1 : Ratios & Proportional Relationships
Write as a unit rate: revolutions in minutes
revolutions per minute
revolutions per minute
revolutions per minute
revolutions per minute
revolutions per minute
revolutions per minute
Divide the number of revolutions by the number of minutes to get revolutions per minute:
,
making revolutions per minute the correct choice.
Example Question #1 : Grade 6
If candidate A receives vote for every votes that candidate B receives. At the end of the election candidate B has votes. How many votes did candidate A get?
In order to solve this problem we need to create a ratio with the given information. It says that for every vote cast for candidate A, candidate B got votes. We can write the following ratio.
Now substitute in the given numbers.
