Question

Ken has read 35 pages of a 120-page book, 53 pages of a 175-page book, and 37 pages of a 155-page book. Part A: Which proportion could you use to represent the percent of pages Ken has read? Part B: What percent of total pages has Ken read? (Round to the nearest percent.)

Answer 1

Ken has read approximately 50% of the total pages.

Step-by-step explanation:

Part A: To represent the percent of pages Ken has read, we can use the following proportion:

(35 + 53 + 37) / (120 + 175 + 155) = x / 100

Let's solve for x:

225 / 450 = x / 100

0.5 = x / 100

So, the proportion is 0.5 = x / 100 to represent the percent of pages Ken has read.

Part B: To find the percent of total pages Ken has read, we can substitute the values into the proportion and solve for x:

0.5 = x / 100

x = 0.5 * 100

x = 50

Therefore, Ken has read approximately 50% of the total pages.
