5 2/4 or 5 1/2
2 2 3 4 4
What is the mode?
2 and 4
1/2 x 1/4 = ?
Give the answer and explain how you would solve this problem.
The answer is 1/8 because you multiply straight across.
1 1/2 x 4 = ?
6
Radius is a 1.75

3.50
5 5/6 / 2/3 = ?
8 9/12 or 8 3/4
1 2 3 4 5
What is the range?
1/2 / 6 = ?
What is the answer? Explain how you solved this.
The answer is 1/12. I gave 6 a leg and did Keep, Switch, Flip to get my answer.

32
8 / 3/4 = ?
10 2/3
4, 2, 1, 6, 9, 11, 10, 8, 5
What is the median?
6
5 / 1/3 = ?
What is the answer? Explain how you solved it
The answer is 15. I gave 5 a leg. Then, I did Keep, Switch, Flip.
2 1/2 x 3 4/5 = ?
9 1/2
The radius of a circle is 15.5
What is the diameter?
31
1 6/7 / 2 3/4 = ?
52/77
6, 5, 12, 4, 3, 9, 7, 2, 1, 10, 8, 11
What is the mode? and why?
all or none because none of the numbers are repeating
4 1/5 x 20 = ?
What is the answer? Explain how you solved it.
The answer is 84. There are two possible explanations. They could have done the box method where they made half a box and multiplied each part out in the box. The other way is to turn 4 1/5 into an improper fraction of 21/5 and multiply by 20/1 before simplifying to get the answer 84.
3 2/3 x 1 1/2 = ?
5 1/2
The diameter of a circle is 85. What is the radius?
42 1/2
4 1/2 / 1 4/5 = ?
2 9/18 or 2 1/2
88, 100, 112, 100, 200
What is the mean?
120
4 1/3 / 1 1/3 = ?
What is the answer? Explain how you solved it.
The answer is 3 3/12 or 3 1/4
I turned both fractions into improper fractions. 13/3 and 4/3. Then I did Keep, Switch, Flip. I multiplied straight across and got 39/12. Then I reduced my answer to get 3 3/12 or 3 1/4.
