Help me please! It's due tomorrow!

15) I'm going to fill in these boxes up to down from left to right and then put the final answer underneath.

1, 4, 2, 20, 1, 10

1/10

16a)8 x 3/4

16b) Draw a bar and cut it into 6 parts. Then divide each part into quarters and group each quarter into groups of three. That will represent the potatoes needed per batch.

16c) Yes, because we know that she has 6 potatoes and if she wants to make 8 batches, she will need to multiply 8 by 3/4. That will come out to be 6 so she has exactly enough to make 8 batches.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
