Fill up :

`7/( - 8 )`   .....   `8/9`

Fill up the blanks: (i) (x,y) = (3, ..), (....,7), (8, 16), (9, ...), (...., 10), (1, 2) (ii) (x,y) = (....,6), (8,3), (12, ...), (16, 3/2), (....,3/4), (48,....)

(A) 7 (B) 8 (C) 6 (D) 9

Multiply : 9/7xx7/8

Fill in the blanks : (i) (-3) + (-9) = ……. (ii) (-7) + (-8) = ….. (iii) (-9) + 16 = ….. (iv) (-13) + 25 = ….. (v) 8 + (-17) = ……….. (vi) 2 + (-12) = ……….

Fill in the blanks: (9)/(8)+(...)=(-3)/(2)

Evaluate : 9/8 times 8/7 ÷ 8/7 + 4/8 + 9/8 times 8/7 times 7/8 + 4/8

Fill in the blanks: 8 1/8-\ =7/8

Evaluate : ( -4/5 ) times ( 5/7 ) times ( -8/9 ) + 8/9 times 4/7
