1. **State the problem:** We need to compare pairs of numbers using the symbols $>$, $<$, or $=$. 2. **Recall the comparison rules:** - If the first number is greater than the second, use $>$. - If the first number is less than the second, use $<$. - If both numbers are equal, use $=$. 3. **Compare each pair:** a) Compare 3984 and 3948: - Since 3984 is greater than 3948, we write $3984 > 3948$. b) Compare 68320 and 68230: - Since 68320 is greater than 68230, we write $68320 > 68230$. c) Compare 490782 and 490729: - Since 490782 is greater than 490729, we write $490782 > 490729$. d) Compare 25.36 and 25.65: - Since 25.36 is less than 25.65, we write $25.36 < 25.65$. e) Compare 38.7 and 8.37: - Since 38.7 is greater than 8.37, we write $38.7 > 8.37$. **Final answers:** a) $3984 > 3948$ b) $68320 > 68230$ c) $490782 > 490729$ d) $25.36 < 25.65$ e) $38.7 > 8.37$
