Solve the following
`7/13 + -9/13 = (--+(-9))/13 = (---)/13`

Solve the following: 3/13 - 2/13 + 5/13

solve the following: 4/13 + -5/8 + -8/13 + 9/13

Add the following: 3/13 + 7/13 + 1/13

Evaluate the following (-9) xx (-13)

(-5)/8+(-9)/13=(-9)/13+(-5)/8

4/13 + 9/13 + 2/13 = ?/13

Re-arrange suitably and find the sum in each of the following: (3)/(5)+(7)/(3)+(9)/(5)+(-13)/(15)+(-7)/(3) (ii) (4)/(13)+(-5)/(8)+(-8)/(13)+(9)/(13)

Solve the equation : 1 + 5 + 9 + 13 + … + x = 1326.
