Answer: The gardener had 3.75 pounds of soil left after using 5/8 of it for his garden
Step-by-step explanation: If the gardener has 10 pounds of soil and he used 5/8 of it for his garden we can find the amount of soil he used as follows: Amount of soil used =(5/8)*10 pounds= 6.26 pounds therefore, the gardener used 6.25 pounds of soil in his garden. Amount of soil left = 10 pounds - 6.25 pounds - 3.75 pounds Therefore, the gardener had 3.75 pounds of soil left after using 5/8 of it for his garden
