Answer:

15 seeds

Step-by-step explanation:

Set up a ratio that represents the problem:

Sown Seeds : Seeds That Grow

100 : 75

Find the unit rate:

The unit rate is when one of the numbers in a ratio is 1. For this problem, let's make the number of sown seeds equal to one.

To do this, divide by 100 on both sides of the ratio.

100 : 75

/100  /100

1 : .75

This means that if Tim sows 1 seed, .75 will grow.

Answer the question:

We need to find the number of seeds that would grow if Tim planted 20 seeds. Therefore, multiply by 20 on both sides of the ratio.

1 : .75

x20  x20

20 : 15

Therefore, if Tim plants 20 seeds, we would expect 15 to grow.
