A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. So the required decimal representation is 8s, as in the question.
seven eights into a decimal = 0.8757/8:= 7 ÷ 8= 0.875 in decimal
seven-eights= 7/8= 7 ÷8=0.875 in decimal
six eights = 6 x 8 = 48
7 eights = 7 x 8 = 56
It is: 4/8 = 0.5 as a decimal
