Question

Find the third proportion to 1 km 500 m and 300 m.

Answer 1

1 km = 1000 m
Therefore, 1500 m : 300 m :: 300 m : ?
1500/300=300/?
5= 300/?
?=300/5
?=60
Therefore the third proportional is 60 m

Answer 2

Dear Student,

● Explaination -

Third proportion = 300√5 m

◆ Explaination -

# Given -

x = 1 km 500 m = 1500 m

y = 300 m

# Solution -

Third proportion of two numbers x and y is given by -

Third proportion = √(xy)

Third proportion = √(1500 × 300)

Third proportion = √450000

Third proportion = √90000 × √5

Third proportion = 300√5 m

Hence, third proportion of 1 km 500 and 300 m is 300√5.

Thanks dear. Hope this helps you...
