Compare 2/3 and 7/12. Which is greater?
Find the COMMON DENOMINATOR.
3 can become 12.
3x4=12 for the new denominator and 2x4=8 for the new numerator.
Now, 8/12 > 7/12 (2/3 is greater.)

Solve for ?
4/10 + ?= 98/100
A) 58/10
B) 94/100
C) 58/100
D) 94/10
We need to find a COMMON DENOMINATOR.
4x10=100.
What you do to the bottom you must do to the top.
Our new equation is 40/100 + ? = 98/100
Answer: 58/100

200
Which fractions are equivalent to 4/6?
A. 8/10
B. 2/3
C. 3/4
D. 8/12
E. 6/9
To find equivalent fractions, you must be able to multiply or divide both the numerator and denominator to find common factors.
Correct Answers:
B. 2/3 because 4 divided by 2 is 2 and six divided by 2 is 3.
D. 8/12 because 4x2=8 and 6x2=12.

Define Ascend
to go up or to go least to greatest
300
Where would you plot 34/100 on a number line?
This would be past the 3/10 mark or 30/100 mark. Also, this would be JUST before the 1/2 mark between 3 and 4 or 30 and 40.

Plot the following decimals on a number line.
.67, 1.06, 1.2, .9
.67 will be three small notches before 7, 1.06 will be six small notches after one whole, 1.2 will be two big notches after one whole and .9 will be one big notch before one whole.

Sadie ordered the following fractions from least to greatest. Do you agree with her reasoning? Why or why not?
2/5, 2/3, 9/16, 11/12
2/3 is greater than 2/5 because they have the same numerator. When dealing with same numerator fractions the smaller denominator wins.
9/16 is JUST over the half mark because half of 16 is 8. So 8/16 would be 1/2.
11/12 is ALMOST a whole. 12/12 would be one whole.
Correct Answer: 2/5, 9/16, 2/3, 11/12.
Remember to draw the number lines or pie graphs to work out each fraction.

Order the following numbers from least to greatest:
2.3 2.09 2.29 2.10
Think of money!
2.09, 2.10, 2.29 and then 2.30
400
Which symbol correctly compares the two fractions?
7/6 and 11/10
- <
- =
- >
- The fractions cannot be compared
7/6 becomes 1 1/6 and 11/10 becomes 1 1/10
1/6 vs. 1/10. Same numerators means the fraction with the smaller denominator wins.
Answer: 7/6 > 11/10

Which is greater 2/3 or 3/4?
3/4 is larger it is closer to a whole.
500
How can we think of decimal form?
We can think of money when dealing with deciamls. One whole (dollars) is on the left side of the decimal point, then the tenths (dimes) is directly to the right of the decimal point and finally, hundreths (pennies) is two places to the right of the decimal point.
