Which number has digits that add up to 13?
Which number has digits that add up to 13?
Step 1: Determine the possible options for the tens digit:
Since the number should be less than 60, the tens digit can only be 5 or 6.
Step 2: Calculate the possible value for the units digit:
The sum of the digits should be 13, so if the tens digit is 5, the units digit should be 13 - 5 = 8. If the tens digit is 6, the units digit should be 13 - 6 = 7.
Step 3: Combine the tens and units digit:
If the tens digit is 5 and the units digit is 8, the number is 58.
If the tens digit is 6 and the units digit is 7, the number is 67.
Therefore, there are two numbers that satisfy the given conditions: 58 and 67.
