Answer 2

The first number is 14

Step-by-step explanation:

Given:

• The ratio of two numbers is 2 : 5

• Second number is 35

To find:

• The first number

Solution :

Let,

First number = 2x

Second number = 5x

Also,

⇒ (Second number) 5x = 35

So,

We can find the value of x by

⇒ 5x = 35

⇒ x = 35 / 5

⇒ x = 7

★ Value of 2x:

⇒ 2 (7)

⇒ 2 × 7

⇒ 14

_________________________

★ Method II:

⇒ 2 / 5 = x / 35

Cross Multiplication :

⇒ 70 = 5x

⇒ x = 70 / 5

⇒ x = 14

__________________________

Therefore,

The second number is 35

The first number is 14
