A drink has 1 part of syrup and 8 parts of water, total 9 parts.
This means a drink has 1 / 9 parts of syrup and 8 / 9 parts of water.
She uses:
1 / 9 ∙ 4.5 = 4.5 / 9 = 0.5 L of syrup
Proof:
She uses:
8 / 9 ∙ 4.5 = 36 / 9 = 4 L of water.
0.5 L of syrup / 4 L of water = 0.5 / 4 = 1 / 8

amount of syrup ---- x L
amount of water ----- 8x L
x + 8x = 4.5
9x = 4.5
x = .5
He uses .5 L or 1/2 L or 500 ml
