Answer : 1. "0.625"
Explanation :

Answer: A) 0.625 Explanation: 5/8 is Nothing but to divide 5 into 8 parts.     As 5 is smaller than 8, the quotient starts with a decimal point to make 5 as 50 to be divisible by 8. (0.)     Now 50 goes for 6 times in 8 leaving a remainder 2. (0.6)      Again 2 is smaller than 8, As it already has decimal point in the quotient, now 2 becomes 20.      Now 20 goes for 2 times in 8 leaving a remainder 4. (0.62)      Again 4 is smaller than 8, As it already has decimal point in the quotient, now 4 becomes 40.     Now 40 goes for 5 times in 8 leaving a remainder 0. (0.625)     Therefore, the decimal value of 58 is 0.625.   Now find a decimal value of 1117 and Discuss your at Discuss.
