Comparing Numbers (Page 58)
Jaspreet and Gulnaz help to keep a record of the number of plates used in the Gurudwara every month. Use the signs < and > to find the month when a larger number of plates were used.
Describe how you decided which number is the bigger one. Which position (Th, H, T, O) helped you to decide this?
Answer:
To determine which number is larger, compare digits from left to right (Th, H, T, O) starting with the largest possible value (Th).
The position that first shows a difference in the digits will determine the larger number. If all digits in the same place value are equal compare the next place value to the right.
