Cameron used 1 1/2 ounces of hydrochloric acid in one experiment. she used 2 1|8 ounces of the acid in a second experiment. how much more acid did cameron use in the second experiment?

5/8
Explanation:
You must subtract the two mixed fractions. 1 1/2 can be written as 1.5. 2 1/8 can be written as 2.125. 2.125 - 1.5 = .625. Since you must convert this back to a fraction, 5/8 = .625.

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
