Question

Mike drank 60% of his glass of milk. Afterwards, 80ml of milk remained in the glass. What volume of milk was initially in the glass?

Answer 1

Answer:

Step-by-step explanation:

$x$ is the total volume of milk.

100% - 60% = 40%

40% is left in the glass.

40% of $x$  = 80 ml

$\frac{40}{100}$ of $x$ = 80

$x = 80$ × $\frac{100}{40}$

$x = 200$ ml
