That's 4/5 or 0.8 .
The answer to three hundred fifteen plus seven hundred eleven is one thousand twenty-six.
Eight over fifteen is. If you could get used to calling those fractions "seven fifteenths" and "one fifteenth", then you'd quickly realize that 7 of anything plus 1 of the same thing is 8 of them.

6/25 + 7/15 = 53/75
No, 7+7=14
It is 2 2/3
75/320 + 96/320 + 80/320 = 251/320
1 and 1 over 16

15/16 + 7/8 is the same as 15/16 + 14/16= 29/16
First we need to convert them into like terms. Three fifths is twelve twentieths. Three fourths is fifteen twentieths. Together that is twenty-seven twentieths. That is one and seven twentieths or 1.35 in decimal.
-9/10 + 3/15 = -6/25... Possibly that's what I think it is...
