• 21 apples for $8
• 35 apples for $14
• 45 apples for $16

3 apples per $ is the greatest unit rate when someone buy 12 apples for $4, because we are able buy more apples with this rate for the same price.

Step-by-step explanation:

As we know that unit rate can be calculated by dividing the two quantities having different units.

For example, Madrid has been champions 10 times in 30 seasons,

i.e. 10 champions / 30 seasons = 0.33 champions per season

and

Barcelona has been champions 5 times in 30 seasons.

i.e.  5 champions / 30 seasons = 0.16 champions per season

Thus, the champion rate for Real Madrid is greater than the champion rate for Barcelona. It means, Real Madrid has been a better team.

Now, let us check and answer the question.

       12 apples / $4 = 3 apples per $

       21 apples / $8 = 2.62 apples per $

       35 apples / $14 = 2.5 apples per $

       45 apples / $16 = 2.81 apples per $

From the above calculations and observation, we can conclude that 3 apples per $ is the greatest unit rate when someone buy 12 apples for $4.

This unit rate is the greatest because we are able buy more apples with this rate for the same price.

In other words, the rate is cheaper than the unit rate of the rest, because can buy more apples with this rate for the same price.

easy math just plug in a and b

step-by-step explanation:

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
