Respuesta :

you would set up this problem by saying 70% over 100 as a fraction and 140 OVER x and cross multiply

140           70
____         ___
x               100                  70x=14,000
                                          Divide         x= number   DONE  
Let
x-------> the number

we know that
[tex]70[/tex] % is equal to [tex] \frac{70}{100} [/tex]
[tex] \frac{70}{100} *x=140[/tex]
multiply by [tex]100 [/tex] both sides
[tex]70*x=14000[/tex]
divide by [tex]70[/tex] both sides
[tex]x=200[/tex]

the answer is
the number is [tex]200[/tex]
