There are 20 cows and 10 farmers in a field. what is the ratio of the number of ears to the number of legs in the field, and what is the significance of this ratio?
3: 5, because for every 3 ears present in the field, there are 5 legs present
3: 5, because on average, there are 3 ears per individual and 5 legs per individual in the field
2: 3, because each farmer has two-thirds the number of ears and legs that a cow has
2: 3, because two-thirds of those in the field are cows, and they have the greater share of ears and legs

3:5, because for every 3 ears present in the field, there are 5 legs present

Step-by-step explanation:

A cow has 2 ears and 4 legs.

20 cows have 40 ears and 80 legs.

A farmer has 2 ears and 2 legs.

10 farmers have 20 ears and 20 legs.

20 cows and 10 farmers have 60 ears and 100 legs.

Ratio of ears to legs is

60:100 = 3:5

3:5, because for every 3 ears present in the field, there are 5 legs present

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

true
