Question

I don't know pls tell ans urgent​

Answer 1

Answer:

let it be

3x+5x = 140

8x = 140

x = 140/8

x= 17.5

so

3x = 3×17.5= 52.5

5x= 5×17.5 = 87.5

Answer 2

so the first part = 140*3/8 = 17.5*3 = 52.5

so the second part = 140*5/8 = 87.5

so if we divide 140 into 3:5 ratio we get 52.5 and 87.5
