A: To find three decimals between 4.333333333(repeating 3) and 4.3, we can add or subtract a small value from each number. Since the repeating decimal 4.333333333... is closer to the number 4.3, let's subtract a small value from it.
Step 1: Taking 4.333333333... - 0.01 = 4.323333333...
Step 2: Taking 4.333333333... - 0.02 = 4.313333333...
Step 3: Taking 4.333333333... - 0.03 = 4.303333333...
Therefore, three decimals between 4.333333333(repeating 3) and 4.3 are 4.323333333..., 4.313333333..., and 4.303333333....
B: To find three decimals between 203.76(repeating 7,6) and 203.7(repeating 7), we can again add or subtract a small value from each number. Since the repeating decimal 203.76(repeating 7,6) is closer to the number 203.7(repeating 7), let's subtract a small value from it.
Step 1: Taking 203.76(repeating 7,6) - 0.01 = 203.75(repeating 7,6)
Step 2: Taking 203.76(repeating 7,6) - 0.02 = 203.74(repeating 7,6)
Step 3: Taking 203.76(repeating 7,6) - 0.03 = 203.73(repeating 7,6)
Therefore, three decimals between 203.76(repeating 7,6) and 203.7(repeating 7) are 203.75(repeating 7,6), 203.74(repeating 7,6), and 203.73(repeating 7,6).
