Question

what is the difference between two whole number is 42. The ratio of two number is 2:5. What are the two numbers​

Answer 1

Answer:

We have,

Let the two whole number is x and y.

Then,

x−y=66......(1)

Now, Acoording to question,

y

x

=

2

5

⇒2x=5y

⇒x=

2

5

y

Put in equation (1) and we get,

x−y=66

⇒

2

5

y−y=66

⇒5y−2y=66×2

⇒3y=66×2

⇒y=

3

66×2

⇒y=22×2

⇒y=44

Put the value of y in equation (1) and we get,

x−y=66

⇒x−44=66

⇒x=66+44

⇒x=110

Then, the number is 110and44

Hence, this is the answer.

Answer 2

Answer:

The two numbers are -28 and -70

Step-by-step explanation:

let the two whole numbers be x and y

= 2x and 5x

their difference = 42

therefore,

2x - 5x = 42

-3x = 42

x = -42/3

x = -14

2x = 2×-14 = -28

5x = 5×-14 = -70
