`5/13-5/13` =

13/5-5/13 =

3/13-2/13+5/13 =

Work out the following : 7/13+2/13-5/13

The point on the line 3x-2y=1 which is closest to the origin is (A) (3/13, - 2/13) (B) (5/11, 2/11) (C) (3/5, 2/5) (D) none of these

Find : a. 4 (5)/(13)- 3 (7)/(13) + 2 (8)/(13)

Choose the correct option (-5)/(13)+?=-1 (a) 8/(13) (b) (-8)/(13) (c)(-18)/(13) (d) (18)/(13)

If [(2+x,3,4),(1,-1,2),(x,1,-5)] is a singular matrix then x is (A) 13/25 (B) -25/13 (C) 5/13 (D) 25/13

Evaluate the difference: 5/(13)-4/(17)

4/13+9/13+2/13=-/13

7/13+(-9)/13=(__+(-9))/13=-/13
