(iii) The difference between x and 9, when x > 9 (iv) The difference between x and y, when x < y (v) b is multiplied by 50. (vi) Product of a and b (vii) z is divided by 10 (viii) 18 divided by a. (ix) 6 times a is added to 3 times b. (x) 3 is subtracted from y. (xi) 5 times x is taken away from 10. (xii) The product of x and y is added to 6 times a. (xiii) The product of a and b is taken away from 3x. .​

Answer 1

i) a + 5

ii) p + q

iii) x - 9

iv) y - x

v) b × 50

vi) a × b

vii) z ÷ 10 or $\frac{z}{10}$ (both are same)

viii) 18 ÷ a or $\frac{18}{a}$ (both are same)

ix)6a + 3b

x) y - 3

xi) 10 - 5x

xii) (x × y) + 6a

xiii) 3x -  (a × b)
