21/5 + 171/3 = 11/5 + 52/3 = 33/15 + 260/15 = 293/15 = 198/15
1 and 2/15
17
2/3 + 1/5 = 10/15 + 3/15 = 13/15
(2/3) + (4/5) = 22/15 or 1.466 (repeating)
One fifth plus one fifth is two fifths (2/5).
5(23)+17-3(2)= 51.
2 to the third power times 5 to the fifth power equals 25,000
1 1/5 + 2 1/3 = 3 8/15
you need to find the common denominator 1/3 + 2/17 = ? 1*17/(3*17) + 2*3/(3*17) = (17 + 6)/(3*17) = 23/51
It is: 3/5+1/3+7/15 = 7/5 or as 1 and 2/5 which is 1.4 as a decimal
14Another answer:-17+17-14+(2*6)+2 = 0
8/15, 8 fifteenths
