Final answer:
To compare 3.58 and 3 4/7, we convert 3 4/7 to a decimal, which is approximately 3.5714. As 3.58 is slightly greater, the comparison is 3.58 > 3 4/7.
Step-by-step explanation:
The student is asking to compare two numbers: 3.58 and 3 4/7. To compare these numbers, first convert the mixed number to an improper fraction or a decimal. For 3 4/7, since there are seven sevenths in one whole, 3 whole numbers would be 21/7 plus the additional 4/7, which totals to 25/7. Converting this to a decimal, we divide 25 by 7, giving approximately 3.5714. Comparing the two decimals, 3.58 is slightly greater than 3.5714. Hence, the correct symbol to place in the box for the comparison is '>'. Therefore, 3.58 > 3 4/7.
