Question

Leonardo correctly answered 0.8 of the questions on his math exam. Liam correctly answered 9/10 of the questions. Keria correctly answered 3/4 of the questions. Who correctly answered the greatest number of questions?

Answer 1

Let's convert them into decimals:
0.8 is already a decimal.
9/10 becomes 0.9 because you divide 9 by 10.
and 3/4 becomes 0.75 because you divide 3 by 4.
Now, which one is the greatest in value? 0.9 is!
So Liam answered the greatest number of question.
Hope this helped!
