Speed = total time divided by time

The semicolon means divide by.

Floret: 4 1/6=6 plus 5/6.

Xiaohong: 47/7=6 and 5/7.

If every digit has the same number, which is 6, then look at the decimal part.

The denominator is different. Divide the denominator before comparing.

Common multiple: 6×7=42

5/6=35/42

5/7=30/42

35/42>30/42

Then 6 5/6 > 6 5/7.

therefore

Xiaohua does it faster.
