Answer 1

for the first one:

You take the number of plain chips and divide it by 3, then multiply by four. You do this because there is a 4 to 3 ratio of hot to plain chips.

42 / 3 = 14, 14 x 4 = 56.

Second one:

Birds (usually) have two wings for each beak. Why? I don't know, ask Darwin. There is a 2:1 (two to one) ratio of wings to beaks.

Third:

50 flaps per second, 60 seconds in a minute. 50 x 60 = 3000.

45,000 / 3000 = 15 minutes.

Fourth:

56 + 120 + 24 = 200

56 / 200 = 28% of the students ate pasta

Answer 2

a)46. Take 42 and divide it by 3. Then multiply 14 by 4.
b)2:1. There are 2 wings for every 1 beak on a bird.
c)15 minutes. multiply 50 times 60 and that's how many times it beats per minute. Then divide 45000 by that number and that's how many minutes it should take.
d) 28%. You have to add all the students together, and you get 200. Then you divide 56 by 200.
