The directions on a seed packet say to plant the seeds 178 inches apart. What is the decimal equivalent of this mixed number?

1.875 inches apart

Step-by-step explanation:

I think you meant "1 7/8 inches."

Convert 7/8 to a decimal fraction. Divide 7 by 8 on a calculator; you will get 0.875. Then: 1 7/8 inches = 1.875 inches.

Plant the seeds 1.875 inches apart.
