Explanation:
Let’s go through each problem one by one and fill in the blanks.
1) “For every 5 boys on a softball team there is 1 girl.”
That means: boys : girls = 5 : 1
So the ratio of boys to girls is
5:1.
2) “The ratio of male to female birds in a bird cage was 5:2.”
This means for every 5 males, there are 2 females.
So: For every
5 males there are
2 females.
3) “At the carnival the ratio of rides to games was 9:8.”
Rides : games = 9 : 8
So: For every
8 games there are
9 rides.
4) “In a bag of candy for every 3 chocolate pieces there are 7 sugar pieces.”
Chocolate : sugar = 3 : 7
So the ratio of chocolate pieces to sugar pieces is
3:7.
5) “At the burger shop the ratio of regular sodas sold to diet sodas sold was 7:1.”
Regular : diet = 7 : 1
So: For every
1 diet soda sold there is
7 regular soda sold.
6) “At the malt shop the ratio of hotdogs sold to hamburgers sold was 7:5.”
Hotdogs : hamburgers = 7 : 5
So: For every
5 hamburgers sold there were
7 hotdogs sold.
7) “At the pet store the ratio of dogs to cats was 6:4.”
Dogs : cats = 6 : 4
So: For every
4 cats there are
6 dogs.
8) “For every 8 Wii games Sarah owned she had 4 PS3 games. What is her ratio of Wii games to PS3 games?”
Wii : PS3 = 8 : 4 → simplify by dividing both by 4 →
2:1
9) “The ratio of cars to trucks in a parking lot was 4:7. For every ___ cars there were ___ trucks.”
Cars : trucks = 4 : 7
So: For every
4 cars there were
7 trucks.
10) “At an icecream shop the ratio of chocolate cones sold to vanilla cones sold was 1:2. For every ___ vanilla cone sold there were ___ chocolate cones sold.”
Chocolate : vanilla = 1 : 2
So: For every
2 vanilla cones sold there were
1 chocolate cone sold.
