Explanation:

Problem 1

Step1: Analyze 64

A two - digit number \(ab\) (where \(a\) is the tens digit and \(b\) is the ones digit) can be written as \(10\times a + b\). For 64, the tens digit is 6 and the ones digit is 4. So 64 has 6 tens and 4 ones.

Step2: Analyze 38

For 38, the tens digit is 3 and the ones digit is 8. So 38 has 3 tens and 8 ones.

Step1: Identify tens digits

The tens digit of 64 is 6 (representing 6 tens) and the tens digit of 38 is 3 (representing 3 tens).

Step2: Compare the tens

Since \(6>3\), 6 tens is greater than 3 tens.

Step1: Recall number comparison

When comparing two - digit numbers, if the tens digits are different, the number with the larger tens digit is larger.

Step2: Compare 64 and 38

The tens digit of 64 is 6 and the tens digit of 38 is 3. Since \(6 > 3\), \(64>38\).

Answer:

64: \(\boldsymbol{6}\) tens \(\boldsymbol{4}\) ones; 38: \(\boldsymbol{3}\) tens \(\boldsymbol{8}\) ones
