It depends:
7/8/9/10 can be:
7/(8/(9/10)) = 7/(80/9) = 63/80, or
7/((8/9)/10) = 7/(8/90) = 7/(4/45) = 315/4
(7/8)/(9/10) = 70/72 = 35/36
(7/(8/9))/10 = (63/8)/10 = 63/80
((7/8)/9)/10 = (7/72)/10 = 7/720

There is an "and" between 8 and 9 so the question, in fact, refers to 7/8 + 9/10 which is not ambiguous.
7/8 + 9/10 = 35/40 + 36/40 = 71/40 = 1 and 31/40
-7/8 is a real number.
10/7 = 13/7
7 over 10 is greater. If you put both of these numbers in decimal you will get 7 over 10 as .7 and 3 over 10 as .3 The number 7 is greater than 3 so 7 over 10 is greater than 3 over 10.
7 over 10 is the rational number 7/10 which is read as seven tenths. It can be convert to a decimal by dividing the numerator by the denominator: 7/10 = 7 ÷ 10 = 0.7
37/10= 3.7 which is as mixed number 3 and 7/10
-7/8 is a real number.
7 over 10
10/7 = 13/7
7 over 10 is greater. If you put both of these numbers in decimal you will get 7 over 10 as .7 and 3 over 10 as .3 The number 7 is greater than 3 so 7 over 10 is greater than 3 over 10.
5/7 is a real number and a rational number.
7 over 10 is the rational number 7/10 which is read as seven tenths. It can be convert to a decimal by dividing the numerator by the denominator: 7/10 = 7 ÷ 10 = 0.7
10 and 7/10
8/5 + 7/10 = 16/10 + 7/10 = 23/10 = 23/10
1 and 3/7
4 and 7/10
It is: 7 and 3/10
7 and 9/10
