0.867 with the 7 digit repeating. According to the video this type of problem is done by multiplying by 100. My answer thus is 8591/9900 which is marked incorrect yet this is the decimal equivalent to the answer given as 781/900. Since I performed the problem as per the second of the two instruction videos and it is the same answer in different from; to be consistent either the video should change or either answer should be acceptable. Both answer are equivalent to 0.867777777778. Thank you.
