Question

Betty is participating in a walk a thon. For every .25 miles she walks, she earns a donation. Betty walks 2.50 miles. How many donations did she earn?

Answer 1

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
