Answer: 2 6/15 < 2 4/9 < 2 3/5 < 2 2/3
Step-by-step explanation:
Answer:
B) 1 8/27
Step-by-step explanation:
First, change all mixed fractions into improper fractions:
2 1/3 = 7/3
1 4/5 = 9/5
7/3 ÷ 9/5
Next, flip the second fraction, and change the division sign into multiplication:
7/3 x 5/9
Multiply across:
7/3 x 5/9 = 35/27
Change into a mixed fraction:
35/27 = 27/27 + 8/27
1 8/27 is your answer.
