Answer 1

Step-by-step explanation:

Let the parts are 7x and 11x

then 11x-7x=20

4x=20

x=5

then the parts are 35 and 55 respectively.

And the number is 35+55 i.e. 90

Answer 2

Answer:

$let \: two \: ratios \: be \: 7x \: and \: 11x \\ \\ according \: to \: condition \: 7x + 20 \: = 11x \: \: \: \: \: \: \: \: \: \: \: \: \\ \: \: - > 20 = 11x - 7x \\ - > 20 = 4x \\ \\ x = \frac{20}{4} = 5 \\ \\ first \: number \: = 11x = 11 \times 5 = 55 \\ second \: number = 7x = 7 \times 5 = 35 \\ \\ the \: whole \: natural \: number \: = 11x + 7x = 55 + 35 = 90$
