Math Problem Statement

Do the 7/100 long division and tell if its terminating or repeating

Solution

To determine if 7100\frac{7}{100} is a terminating or repeating decimal, we can perform the long division of 7 divided by 100.

Long Division:

  1. 7.000 ÷ 100:
    • 100 goes into 70 zero times, so we write 0 as the first digit of the quotient.
    • Bring down the 0 to make 70, which still isn't enough for 100.
    • Bring down another 0 to make 700.
    • 100 goes into 700 exactly 7 times.

So, 7100=0.07\frac{7}{100} = 0.07.

Conclusion:

The decimal representation of 7100\frac{7}{100} is 0.07, which terminates after two decimal places. Therefore, it is a terminating decimal.
