I think you're referring to the notation for a repeating decimal.
So it is 175.877777.... Well 0.777777.... is 7/9, and 0.87777 - 0.77777 = 0.1 = 1/10. so it is 175 + 7/9 + 1/10 which is 175 + 70/90 + 9/90 = 175 79/90
It is 0.7142857... with the underlined string repeating.
.875 = 7/8
7/16
When a fraction is reduced to lowest terms, the only factor that the numerator and denominator have in common is 1. For example, the fraction 7/15 is reduced to lowest terms. The factors of 7 are 1 and 7, and the factors of 15 are 1, 3, 5 and 15. The only factor they have in common is 1.
The easiest way is to just find a common denominator. You will have to first turn your mixed fraction into an improper fraction. For example 8/7 and 1 and 2/7 is an example of an improper fraction and a mixed fraction. think of 1 and 7/7 and add it to 2/7 so 1 and 2/7 is 9/7. Now add 9 and 8 and the answer is 17/7. In some cases, you will need to find a common denominator after changing the mixed fraction into an improper one. 3/2 and 1 and 2/5 is an example 1 and 2/5 is 7/5 and to add fifths and halves you need a common denominator of 10 So 3/2 is 15/10 and 7/5 is 14/10, now add them and you have 14+15 =29/10
It is 0.7142857... with the underlined string repeating.
7/100
7 / 100
.875 = 7/8

The answer depends on what string is repeating. It is not clear from the question whether the recurring fraction is meant to be0.428571428571... or0.4285712857128571... or0.428571285718571... or0.428571571571... or0.4285717171...0.4285711111...where the underlined strings are repeating.
write a proper fraction with a denominatorthe is common to 7/8
7/8 and 1/8 have common denominators
1/6 + 1/7 needs to have common denominators to be successfully added. 6 and 7 are most common multiples of 42. We can achieve the common denominator by multiplying the fraction by the denominator of the other fraction. 1/6 (7) + 1/7 (6) = 7/42 + 6/42 = 13/42 which is the simplest form of the fraction.
If you mean the highest common factor then it is 7
Start by changing to a fraction 7/100 Since there is no common divisor (dividing number) that's it Easy one!
