Answer 2

To compare these fractions, you can cross-multiply to find equivalent fractions with a common denominator. Here's the comparison step by step:

1. 2/7 : 5/11

   • Cross-multiply: (2 * 11) / (7 * 5) = 22/35.

2. 2/5 : 3/4

   • Cross-multiply: (2 * 4) / (5 * 3) = 8/15.

3. 4/7 : 13/56

   • Cross-multiply: (4 * 56) / (7 * 13) = 224/91.

4. 56/7 : 19/5

   • Cross-multiply: (56 * 5) / (7 * 19) = 280/133.

So, the comparisons are as follows:

• 2/7 : 5/11 = 22/35
• 2/5 : 3/4 = 8/15
• 4/7 : 13/56 = 224/91
• 56/7 : 19/5 = 280/133
