5/4 or 1 and 1/4
6 and 4/10 + 5 and 3/10=
11 and 7/10
Compare using <, >, or =
1/2 ___ 3/4
1/2 < 3/4
True or False?
7+ 2/3= 7 and 2/3
True.
12 x 2/3=
24/3 or 8
3 and 1/4 + 4 and 3/4=
6
Compare.
6 __ 45/5
6 < 45/5
We can change 45/5 into a whole number to compare by counting by 5's. 45/5=9 and 9 is greater than 6.
Convert 14/3 into a mixed number.
4 and 2/3
Why is 4 x 2/3 equal to 8 x 1/3?
We multiply the whole number by the numerator and 4 x 2= 8 and 8 x 1=8. The denominator stays the same.
True or False?
11 + 2/3= 13/3
False.
11 + 2/3= 11 and 2/3
Compare.
11 and 1/3 ____ 34/3
11 and 1/3 = 34/3
Convert 4 and 5/6 into an improper fraction.
29/6
Rewrite 4 x 3/8 as the product of a unit fraction and a whole number.
4 x 3/8= 12/8
We can rewrite this using a unit fraction as 12 x 1/8. Remember unit fractions always have a numerator of 1.
5 and 2/5 - 1 and 3/5=
3 and 4/5
We cannot subtract 2/5 from 3/5 so we have to convert both mixed numbers to improper fractions and then subtract.
Compare.
2 and 5/8 _____ 2 and 1/2
2 and 5/8 > 2 and 1/2
Compare 13/6 _____38/12
13/6 < 38/12
We can make common denominators so 13/6= 26/12 and 26/12< 38/12.
True or False?
7/8 + 7/8 + 7/8= 3 x 7/8
True
Make a pattern of 5 fractions by adding 5/2 to 1/2 and then continue to add 5/2 to each fraction. Circle each fraction equal to a whole number.
1/2, 6/2, 11/2, 16/2, 21/2
6/2= 3
16/2=8
Using benchmark fractions explain why 5/6 is less than 6/5.
5/6 is one sixth away from a whole. 6/5 is larger than one whole by one sixth, so 6/5 is more than 5/6.
Rewrite 4 x 2 and 1/3 as the product of a unit fraction and a whole number.
28/3 or 9 and 1/3.
We have to convert 2 and 1/3 into an improper fraction and then we can multiply.
