In one day, the candy store makes 100 lollipops and 5 hard candies. They do not use food colouring in anything else. The store has used 600ml of food colouring by the end of the day. How much food colouring, in millilitres, does each hard candy need?```
N'ụzọ ahịa akwụkwọ ọtụtụ akwụkwọ nri. Ọ bụrụ na ọnụ ọtụtụ na-eme 5ml nri nri, ma ọ bụrụ na ọnụ ọtụtụ na-eme nri nri. Na ụbọchị ọzọ, ahịa akwụkwọ na-eme 100 lollipops na 5 akwụkwọ nri. Ha adịghị ekwesị nri nri na ọdịda ọzọ. Ahịa na-eme 600ml nri nri na ọsọ. Kedu ihe ọ bụla nri nri, na millilitres, ka ọnụ ọtụtụ na-eme?``` <response>: N'ihi na nke a, ndị na-ewere ihe ọ bụla na-akpọ 5ml nri odo * 100 lollipops = 500ml nri odo.
Nke a bụrụ na ndị na-ewere ihe ọ bụla na-akpọ 600ml nri odo - 500ml nri odo maka lollipops = 100ml nri odo.
N'ime ihe ọ bụla hard candy na-akpọ 100ml nri odo / 5 hard candies = 20 ml nri odo.

Nke a bụ ihe ọ bụla: 20.```
