Researchers asked 250 families whether or not they had homeowners and how many cars they had. The responses are summarized in the following table

(a) what are the percentages of the families that are not homeowners

(b) what percentage of the families have no car for one car

a. The percentage of the families that are not homeowners is 52%.

b. The percentage of the families have no car or one car is 26%.

The percentage of a number is when the fraction of a number is multiplied by 100. Percentages are represented with this sign '%'.

Percentage of the families that are not homeowners =  (sum of families that have no car, one car, two cars or more cars / total number of families surveyed) x 100

× 100

 × 100  = 52%

Percentage of families that have no car or one car = ( sum of homeowners and families that are not homeowners) x 100

x 100

x 100 = 26%

Total of non home owners is 45 + 85 = 130

Percentage would be 130/250 = 0.52

0.52 x 100 = 52%

Number who have no car or one car = 20 + 45 = 65

Percentage = 65/250. = 0.26 = 26%
