Example Question #13 : How To Find A Ratio
One dollar is equal to about 116.76 Japanese yen. For how many yen should a tourist to Japan be able to exchange $2,500 at that rate (nearest whole yen)?
One dollar is equal to 116.76 yen, so multiply $2,500 by this conversion rate to get
yen.
Example Question #14 : Numbers And Operations
Sharon is having a birthday party. So far, she has invited twenty of her friends from school, nine of whom are girls. She wants to make the ratio of boys to girls at the party two to one. If she decides to add her two cousins, both girls, to the guest list, and no other girls, how many more boys does she need to invite?
So far, Sharon has invited twenty friends from school - eleven boys and nine girls. Including Sharon's cousins and Sharon herself, there are eleven boys and twelve girls.
For there to be a two-to-one boy-to-girl ratio, Sharon must have twice as many boys as girls. She will need boys total, so she will need to invite more boys.
Example Question #681 : Ssat Middle Level Quantitative (Math)
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 : Ratios & Proportional Relationships
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.
We know that candidate B received votes. Write a new ratio.
Now, use the original relationship to create a proportion and solve for the number of votes that candidate A received.
Cross multiply and solve for .
Simplify.
Divide both sides of the equation by .
Solve.
