Question

the sum of 2 numbers is 2145 and one of then is half the other find the number​

Answer 1

Answer:

The numbers are 1430 and 715

Step-by-step explanation:

Let first number be y

Then other number is 1/2 of y

It's given that sum = 2145

$y+ \frac{1}{2} y = 2145$

$\frac{3}{2}y = 2145$

$y = \frac{2145 \times 2}{3}$

$y = 715 \times 2$

$y = 1430$

So the number are

y = 1430

and 1/2 of y = 715

Answer 2

Step-by-step explanation:

let the no. be x

so other no. =1/2x

1/2x+x=2145

3/2x= 2145

x = 2145*2/3

x = 1430

1/2x =1/2*1430 = 715
