Comparing Fractions
Compare 4/5 and 4/7- which is greater?
4/5 > 4/7 because the same amount is shaded but the parts are bigger!
Add 1/7 + 5/7 + 3/7
9/7 or 1 2/7 (both ok!)
Multiply 8 X 5/7
40/7 or 5 and 5/7!
Compare 1 & 2/6 and 9/6 using <, >, or =
1 2/6 < 9/6
because 1 2/6 can be converted to 8/6!
Add 2 & 3/4 + 1 & 3/4 and write your answer as a mixed number.
2 3/4 + 1 3/4 = 3 6/4 = 4 2/4
Convert 15/4 to a mixed number
15/4 = 4/4 + 4/4 + 4/4 + 3/4 = 3 3/4
Compare 6/7 and 8/10 using <, >, or =
6/7 > 8/10
Butterfly method:
6/7 = 60/70
8/10 = 56/70
Subtract 4 & 2/8 - 2 & 3/8.
4 2/8 - 2 3/8 = 2 2/8 - 3/8 = 1 7/8
Litzy argues that 6/10 is equal to 3/5. Mr. Chavez argues that 6/10 is equal to 1/2. Who is right?
MAKE AN EQUATION using multiplication or division to show how you know.
6/10 = 6 ÷ 2 / 10 ÷ 2 = 3/5
Litzy is correct!
Compare 2/5 and 4/7 using <, >, or =. THEN, explain how you know which is greater using your knowledge of benchmark fractions (0, 1/2, and 1).
The strongest response will say that 2/5 is less than 1/2, and 4/7 is greater than 1/2, so we therefore know 2/5 is less than 4/7! You can also say 2/5 is closer to 0 and 4/7 is closer to 1
A fraction pattern starts at 2/3 and then adds 4/3 each time:
2/3, 6/3, ...
Make the pattern go until 34/3, and CIRCLE any whole numbers you find!
2/3, 6/3, 10/3, 14/3, 18/3, 22/3, 26/3, 30/3, 34/3
Circled fractions are: 6/3 (2 wholes!), 18/3 (6 wholes!) and 30/3 (10 wholes!)
