• The most easy way to do it is :
if u have 4/6 find the equivalent fraction for it
2+2=4
3+3=6
so 2/3 is equivalent for 4/6 but some other fractions don't have this method. So if u want me to do an easy method for the other fractions make this comment 10 likes 👍
• You could also try the butterfly method!

4 5
- -
6 7
Multiply the 6 and the 5, 6x5=30
Then multiply the 7 and 4, 4x7=28
The side with a bigger number is the greater one.
• Can you explain it a little more please? I didn't get it.
• how do you know what to cross out?
• What if there are no answers?
• what if the number is bigger then the other number
• then just do it half it will be the same thing.
• How do you do the 2/3rd trick?
• Easy just subtract 1 from each number.

• `1` divided by `0` is `undefined`.
One way to see why, is that no number when multiplied by `0` will get you `1`.
