Question

Si la razon de dos numeros a y b es 3/8 calcula
a, si b=24
a, si b=-15
a, si b= 1,5
a, si b= -16

Answer 1

¨*Sólo reemplazas el valor de "b"y despejas "a".
                                   a/b = 3/8

* Si b = 24; a = 9
a/24 = 3/8
a = 24*3/8
a = 9

* Si b = -15 ; a = -45/8
a/-15 = 3/8
a = -15 * 3/8
a = -45/8

* Si b = 1.5 ; a = 9/16
a/1.5 = 3/8
2a/3 = 3/8
a = 3/8 : 2/3
a = 9/16

* Si b = -16 ; a = -6
a/-16 = 3/8
a = -16*3/8
a = -6
