3\frac{5}{7} - 1\frac{16}{21}

Solution Transcript

🎙️

To subtract 3, and 5 over 7 minus 1, and 16 over 21, first notice that 21 is 3 times higher than 7. So, multiply top and bottom of the first fraction by 3. Then your first fraction is 3 and 15 over 21. Now, convert any whole numbers to add them to numerators. From there, you can subtract the numerators as you normally would.
