Question

Tim grows linflowers from seeds. But not all of his seeds start to grow. He has found that for every 100 seeds he sows, only about 75 start to grow. a. Tim sows 20 linflower seeds. How many would you expect to grow?

Answer 1

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.
