Answer 1

5/12=20/48<11/16=33/48

10/27=280/756<15/28=405/756

Answer 2

Comparing Fractions Without Finding a Common Denominator

When comparing fractions without finding a common denominator, you can use cross-multiplication to determine which fraction is greater.

Comparing 5/12 and 11/16: To compare 5/12 and 11/16, cross-multiply to get 5*16 and 11*12. This results in 80 and 132, respectively. Since 132 is greater than 80, 11/16 is greater than 5/12.

Comparing 2/3 and 3/7: For 2/3 and 3/7, cross-multiply to get 2*7 and 3*3. This results in 14 and 9, respectively. Since 14 is greater than 9, 2/3 is greater than 3/7.

Comparing 4/5 and 3/8: Cross-multiplying 4/5 and 3/8 gives 4*8 and 3*5, resulting in 32 and 15, respectively. Since 32 is greater than 15, 4/5 is greater than 3/8.

Comparing 10/27 and 15/28: Cross-multiplying 10/27 and 15/28 gives 10*28 and 15*27, resulting in 280 and 405, respectively. Since 405 is greater than 280, 15/28 is greater than 10/27.

I hope this helps! If you have any other questions, feel free to ask.
