Question

35% de a es 4 y 6 es el 12% de b entonces b/a es?

Answer 1

Tenemos.

35% *a = 4
35/100 * a = 4
35a/100 = 4
35a = 4*100
35a = 400
a = 400/35         Simplificamos sacas 5ta
a = 80/7


12% * b = 6
12/100 * b = 6
12b/100 = 6
12b = 6 * 100
12b = 600
b = 600/12
b = 50

Hallar b/a
50/(80/7) =
50 * 7/80 =
(50 * 7)/80 =        Simplificas ceros
(5 * 7)/8 =
35/8
