how do I divide 64 bundles of newspaper in2 two groups so the ratio is 3:5

Answer 1

Let x = the smaller bundle

3/8 = x/64

Cross multiply and solve for x.

8x = 192

x = 24

64 - 24 = 40

24/40 = 3/5

Answer 2

or
let the bundles contain 3x and 5x papers
3x+5x=64
8x=64
x = 8
so 3x ---> 24
and 5x ---> 40
