Let's start by seeing what percentage is incorrect.
100-85=15
So, 15% is incorrect when answering 3 problems wrong. So let's divide 15 by 3.
15÷3=5
So, each problem is worth 5%, let's divide 100 by 5. The reason I'm doing thiis is to find how many questions are on the quiz, since if you got them all right, it's 100.
100÷5
20
There are 20 questions, let's make sure this is correct.
If she got 3 wrong, she got 17 right. Let's calculate her percentage and make sure it is the right one.
17÷20
.85×100
85%
So, there are 20 questions on the math quiz.
Answer: 1 2/6 which needs to be simplify which is 1 1/3.
The answer for 5+b=25 isb=20
2 x 5 x 11 Is it I think. What do you think?
There is 100 cm in 1 meter so if thats true then you must take
345/100
and that should be your answer :)
