The decimal expansion of 3/7

Question

Maths all

Answer 1

divide 7 into 3 and divide 6 times (add 6 zeros) to get the repetend; when you divide the seventh time the repetend will start to repeat

 

3/7=0.428571428571428571428571...

again, always divide the denominator into the numerator and divide until you clearly see what repeats

the repetend cannot exceed 1 less than the denominator; sometimes you get the maximum number of digits and sometimes you don't

when the denominator is 7 you get the maximum number of digits (7-1=6)
