Given 0.6 M of sucrose solution, how can I dilute this to 0.5M sucrose solution?

My classmates suggests that using ratio to work out the answer.
Like
0.5M/0.6M = x /6

so, get 5 cm³ of sucrose solution from the 0.6M sucrose soln and add ONE cm3 of water.

The final soln will be 0.5M.

But, anyone knows what's the principle? How does this work?
I once used, M₁V₁=M₂V₂, but I don't get any clue.

How can we take out 5 portions of the 0.6M sucrose soln and add one cm³ to dilute this to 5 cm³?
