Answer

The fewest people responded 4 hours. 153 people responded 4 hours.

Work Step by Step

You can look at the circle graph and visually confirm that the smallest portion is the portion colored green. The green section is for the response of 4 hours, so 4 hours was the response given by the fewest people. The circle graph indicates that $\frac{3}{20}$ of the people surveyed responded 4 hours. 1020 people were surveyed, so multiply 1020 by $\frac{3}{20}$ to find the number who responded 4 hours. $1020 \times \frac{3}{20} = \frac{3060}{20} = \frac{306}{2} = 153$
