Question

If the first, second and fourth terms of a proportion 3,11 and 55 find the third term

Answer 1

Answer:

• The third term is 8.

Step-by-step explanation:

Given that:

• The first, second and fourth terms of a proportion 3, 11 and 55.

Let us assume:

• The third term be x.

To Find:

• The third term.

Finding the third term:

• According to the question.

⟶ 3 : 11 : : x : 55

⟶ 3/11 = x/55

• Cross multiplication.

⟶ 11 × x = 55 × 3

⟶ 11 × x = 11 × 5 × 3

• 11 cancelled both sides.

⟶ x = 8

∴ The third term = 8

Answer 2

Answer:

The third term is 8.

Given:

▶ The first, second and fourth terms of an proportion 3,11 and 55.

To Find:

▶ The third term.

Solution:

Let the third term be ‘x’.

A/C,

⟹ 3 : 11 : : x : 55

⟹ 3/11 = x/55

Cross multiplication.

⟹ 11 × x = 55 × 3

⟹ 11 × x = (11 × 5) × 3

11 gets cancelled on both sides.

⟹ x = 5 + 3

⟹ x = 8

Therefore,

The third term is 8.
