Question

1. nanci is volunteering at the animal shelter. she wants to spend an equal amount of time playing with each dog. she has 145 minutes to play with all 7 dogs. about how much time can she spend with each dog?

Explanation:

Step1: Identify division for equal time

We need to divide total time by number of dogs: $\frac{145}{7}$

Step2: Estimate the quotient

Round 145 to 140 (a multiple of 7): $\frac{140}{7}=20$. Since 145 is slightly more than 140, the value is a bit over 20, so we estimate to 20.

Answer:

About 20 minutes
