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
