Question

the first third and fourth term of a proportion are 15 40 and 120 respectively find the second term​

Answer 1

Answer:

The second term is 45

Step by step Explanation:

First, let the second term be y

So, 15, y, 40 and 120 are in proportion.

Product of extreme terms are equals first and last term ( 15 × 120 )

Product of mean terms equals the second and third terms ( y × 40 )

Because they are in proportion, 15 × 120 = y × 40

1800 = 40y

divide by 40

y = 1800/40

y = 45

The second term is 45
