`(a) square - 5/8 = 1/4`
(b) `□ − 1/ 5 = 1/ 2`
(c)` 1/ 2 − □ = 1/ 6`

Replace ( ) by the correct number: (\ )-5/8=1/4 (ii) (\ )-1/5=1/2 1/2-\ (\ )=1/6

Simplify : (8) 1/4 - (2) 5/6

The correct fraction in the box (\ ) is (\ ) - 5/8 = 1/4 (a) 6/8 (b) 7/8 (c) 1/2 (d) None of these

int(x^9dx)/((4x^2+1)^6) is equal to (a) 1/(5x)(4+1/(x^2))^(-5)+c (b) 1/5(4+1/(x^2))^(-5)+c (c) 1/(10)(1+4x^2)^(-5)+c (d) 1/(10)(4+1/(x^2))^(-5)+c

The ends of a diagonal of a square are (2,-3) and (-1,1)dot Another vertex of the square can be (a) (-3/2,-5/2) (b) (5/2,1/2) (c) (1/2,5/2) (d) none of these

((-1)/2)^5*\ ((-1)/2)^3 is equal to (a) ((-1)/2)^8 (b) -\ (1/2)^8 (c) (1/4)^8 (d) (-1/2)^(15)

Solve (a) 2/3 + 1/7 (b) 3/10 + 7/15 (c) 4/9 + 2/7 (d) 5/7 + 1/3 (e) 2/5 + 1/6 (f) 4/5 + 2/3 (g) (3/4) (1/3) (h) (5/6) (1/3) (1) 2/3 + 3/4 + 1/2 (1) 1/2 + 1/3 = 1/6 (k) (1) 1/3 + (3) 2/3 (1) (4) 2/3 +(3) 1/4 (m) ((16)/5))(7/5)
