Question

La suma de dos numeros es 1,05 y su diferencia es 0,45. Hallar los números. Luego pasa la expresion decimal a fraccion​

Answer 1

Answer:

We have that x + y = 1,05 = 105/100 (i)

And x - y = 0,45 = 45/100 (ii)

So, from equation (i) we get

x = 105/100 - y (iii). Now, substituting x in equation (ii) we have

2y = 3/5 and hence y = 3/10. Finally, substituting y in equation (iii) you get

x = 105/100 - 3/10 = 75/100 = 3/4. Therefore you have x = 3/4 and y = 3/10
