Liz has added 20% of the total amount of acid that she needs
in the beaker for her experiment. She has put in 10 ml so far.
How much more does she need to add? Plz help

Respuesta :

40mL
20%= 1/5
10*5=50
Since 10 is 1/5 of 50 and the question is how much more, subtract it from 50 and you get 40.


Sorry if it’s hard to understand. I did it in my head and it’s hard to explain when you know how to do it lol.
