Seven fifteens is 105. If you mean 7 fifteenths, it is already in its lowest terms.

the sum of -2 and 6 and 7 is (-2+6+7)

(1/3)+(2/15)=(5/15)+(2/15)=7/15 so, seven fifteenths.

Sum(not div by 7) = Sum(all) - Sum(div by 7) Now the sum of an AP is Sn = n/2 (first + last) where n is the number of terms Sum(All) = 10000/2 (1 + 10000) = 50005000 Sum(div by 7) = (9996/7)/2 (7 + 9996) = 1428/2 (10003) = 7142142 Sum(not div by 7) = Sum(all) - Sum(div by 7) = 50005000 - 7142142 = 42 862 858

Sum of is a grouping symbol. 7*(2+5)

what is the sum of 7 and a number is more than 2?

Sum of is a grouping symbol. 7*(2+5)

7/10 = .7 9/15 = .6. Winner - 7/10

10/15 = 2/3

Its digital sum is: 2+2+3 = 7

the sum of 10 and the product of 7 and a number 2+5=7 2*5=10

sum means addition so the sum of 5 and 2 will be 7
