The problem asks us to categorize multiplication expressions into three groups based on whether the product is greater than 60, equal to 60, or less than 60. The expressions are: $60 \times \frac{1}{3}$, $60 \times 1$, $60 \times \frac{5}{4}$, $60 \times \frac{1}{5}$, and $60 \times \frac{5}{6}$.

0. The expressions are: $60 \times \frac{1}{3}$, $60 \times 1$, $60 \times \frac{5}{4}$, $60 \times \frac{1}{5}$, and $60 \times \frac{5}{6}$.

2. Solution Steps

First, we calculate the value of each expression:
60×13=603=2060 \times \frac{1}{3} = \frac{60}{3} = 20
60×1=6060 \times 1 = 60
60×54=60×54=3004=7560 \times \frac{5}{4} = \frac{60 \times 5}{4} = \frac{300}{4} = 75
60×15=605=1260 \times \frac{1}{5} = \frac{60}{5} = 12
60×56=60×56=3006=5060 \times \frac{5}{6} = \frac{60 \times 5}{6} = \frac{300}{6} = 50
Now, we categorize each expression based on its value compared to 60:
Product > 60: 60×54=7560 \times \frac{5}{4} = 75
Product = 60: 60×1=6060 \times 1 = 60
Product < 60: 60×13=2060 \times \frac{1}{3} = 20, 60×15=1260 \times \frac{1}{5} = 12, 60×56=5060 \times \frac{5}{6} = 50

3. Final Answer

Product > 60: (60×54)(60 \times \frac{5}{4})
Product = 60: (60×1)(60 \times 1)
Product < 60: (60×13,60×15,60×56)(60 \times \frac{1}{3}, 60 \times \frac{1}{5}, 60 \times \frac{5}{6})
