Question

The length a line segment PQ is 22 cm. Point R divide the line segment in the ratio 5:6. What is the length of PR? Fatio and Proportion​

Answer 1

Answer:

PR=10 cm

Step-by-step explanation:

it is given that on seg.PQ,P-R-Q

hence ,PR+RQ=PQ

5x+6x=22

11x=22

x=22÷11

x=2

length of PR =5x=5×2

=10

Answer 2

Given:

PQ=22cm

The ratio of dividing PQ=5:6

To find:

The measure of PR

Solution:

The measure of PR is 10 cm.

The given line PQ is equal to 22 cm and is divided by R into two parts in the ratio of 5:6.

So, PR: RQ=5:6

The measure of PR=5/11 of PQ

=5/11×22

=5×2

=10 cm

Therefore, the measure of PR is 10 cm.
