Question

The points J, K, L and M all lie on the same line segment, in that order, such that the ratio of JK: KL: LM is equal to 1:4:4. If JM = 45, find JL.

Answer 1

J, K, L, M

1 : 4 : 4

JM = 45

JL = ?

There are 9 units in all the segment ( 1 + 4 + 4 = 9)

So, divide 45 by 9

45/9 = 5

Find JL

In JL there are 5 units, so multiply 5 by 5.

5 x 5 = 25

JL = 25
