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.
