She earned 10 donations.
2.50 ÷ .25 = 10
To double check you can go 10 × .25 = 2.5 then you just add the zero at the end and it becomes 2.50
Since there are 8 cookies out of 20 cookies, the probability of randomly choosing a chocolate chip cookie would be 8 out of 10, or 8/10 if you prefer fractions.
However, the fraction 8/10 can still be simplified. Divide the numerator and denominator by 2 to get 4/5.
4/5 --> 4 divided by 5 = 0.8
So the answer is 4/5 or 0.8.
4b - 24 + 19 = 4b - (-24 + 19) = 4b - 5
