Question

2-65 find the missing lengths in the problem below. assume each line segment is subdivided into equal sections. show your work. a) ? 0 20 b) ? 0 60

Explanation:

Step1: Determine segment - size for part a

The line from 0 to 20 is divided into 4 equal - length segments. So the length of each segment is $\frac{20}{4}=5$.

Step2: Calculate the missing length for part a

The missing length covers 2 segments. So the length is $2\times5 = 10$.

Step3: Determine segment - size for part b

The line from 0 to 60 is divided into 6 equal - length segments. So the length of each segment is $\frac{60}{6}=10$.

Step4: Calculate the missing length for part b

The missing length covers 3 segments. So the length is $3\times10 = 30$.

Answer:

a) 10
b) 30
