Question

use the number line below to determine the ratio of bc to gk. a b c d e f g h i j k 0 20 40 60 80 100 a. 5:1 b. 4:1 c. 1:5 d. 1:4 please select the best answer from the choices provided

Explanation:

Step1: Find length of BC

The coordinate of B is 10 and C is 20. So $BC=20 - 10=10$.

Step2: Find length of GK

The coordinate of G is 60 and K is 100. So $GK = 100 - 60=40$.

Step3: Calculate the ratio

The ratio of BC to GK is $\frac{BC}{GK}=\frac{10}{40}=\frac{1}{4}=1:4$.

Answer:

D. 1:4
