Devin Denominator studied hard for his tests last week. He answered 90% of the math test questions and 80% of the history test questions correctly. If each test had 50 questions, how many questions did Devin answer correctly?
on the math test he answered 45 of the questions correctly. I multiplied 50 times .9.
ReplyDeletethen I got my answer of 45.
On the history test he got 40 of the answers correct. I got my answer by multiplying 50 times .8. i turned the % into a decimal.
