Avial contains 20 ml of medicine. if each dose is 1/8 of the vial, how many ml is each dose? express your answer as a decimal.

Multiply total number of ml (20 ml) by the fraction size (1/8).

= 20 * 1/8
multiply numerators (top)
= (20*1)/8
= 20/8

= 2 4/8
reduce fraction by 2
= 2 1/2 ml or 2.5 ml

ANSWER: Each dose contains 2.5ml
