Which of the following numbers has a terminating decimal?
15/600, 29/343, 7/(2$$^2$$​×7²),77/210

Correct option is C

Given:

15/600, 29/343, 7/(2$$^2$$​​×7²),77/210

Solution:

a terminating decimal =​a decimal number with a finite number of digits after the decimal point.

​15/600=0.025

29/343 =0.1193415638

7/(2$$^2$$×7$$^2$$​ )=0.035714

77/210 =0.36666666

so number 15/600=0.025 a terminating decimal.

a terminating decimal is possible when the denominator is multiple of either 2 or 5.
