You mix soda water, fruit punch concentrate, and ginger ale in the ratio of 1 : 2 : 5 to make fruit punch. How many pints of each ingredient should you use to make 4 gallons of fruit punch?

Answers

so the ratio is 1 to 2 to 5
so basically 1 unit of soda water to 2 units of fruit punch to 5 units of ginger ale

total is 1+2+5=8 units

so 4 gallons=8 units
divide by 8
1/2 gallon=1 unit

soda water=1 unit=1/2 gallon
fruit punch=2 unit=1/2 times 2=1 gallon
ginger ale=5 unit=5 times 1/2=5/2=2 and 1/2 gallon

soda water=1/2 gallon
fruit punch concentrate=1 gallon
ginger ale=5/2 gallon or 2 and 1/2 gallon

Answers

Q1. The answer is d) 13 to 18

There are 13 pens and 18 pencils. Ratio of pens to pencils can be written as:
pens : pencils

Since pens = 13 and pencils = 18, then 
pens : pencils = 13 : 18

Or in other words, ratio of pens to pencils is 13 to 18. Thus, choice d) is correct.


Q2. The answer is C.5 to 8

There are 12 tulips and 20 roses. The total number of flowers is 12 tulips + 20 roses = 32 flowers. Ratio of roses to the total number of flowers can be written as:
roses : total flowers

Since roses = 20 and total flowers = 32, then 
roses : total flowers = 20 : 32

Now, let's simplify 20 to 32 ratio:
20 : 32 = (20 / 4) : (32 / 4) = 5 : 8 

Or in other words, ratio of roses to the total number of flowers is is 5 to 8. Thus, choice C. is correct.


Q3. The answer is 3 : 4

There are 30 one-story homes and 24 two-story homes. Ratio of two -story homes to one-story homes can be written as:
two-story homes : one-story homes

Since one-story homes = 32 and two-story homes = 24, then 
two-story homes : one-story homes = 24 : 32

Now, let's simplify 24 to 32 ratio:
24 : 32 = (24 / 8) : (32 / 8) = 3 : 4

So, the ratio of one-story homes to two-story homes is 3 to 4.


Q4. The answer is 

There are 16 trading cards and 2 wildlife cards. Ratio of wildlife cards to total trading cards can be written as:
wildlife cards : trading cards

Since trading cards = 16 and wildlife cards = 2, then 
wildlife cards : trading cards = 2 : 16

Now, let's simplify 2 to 16 ratio:
2 : 16 = (2 / 2) : (16 / 2) = 1 : 8

So, the ratio of wildlife cards to total trading cards is 1 : 8



Q5. The answer is

There are 3 cobblers. The total number of baked goods is 12 cookies + 9 pies + 8 cakes + 4 tarts + 3 cobblers = 36 baked goods.  Ratio of the total number of baked goods to cobblers can be written as:
baked goods : cobblers

Since baked goods = 36 and cobblers = 3, then 
wildlife cards : trading cards = 36 : 3

Now, let's simplify 36 to 3 ratio:
36 : 3 = (36 / 3) : (3 / 3) = 12 : 1

So, the ratio of the total number of baked goods to cobblers is 12 : 1
