Question

Write the following using numbers, literals and sings of basic operations:

(i) The sum of 6 and x.
(ii) 3 more than a number y.
(iii) One-third of a number x.
(iv) One-half of the sum of number x and y.
(v) Number y less than a number 7.
(vi) 7 taken away from x.
(vii) 2 less than the quotient of x by y.
(viii) 4 time x taken away from one-third of y.
(ix) Quotient of x by 3 is multiplied by y.

Answer 1

(i) The sum of 6 and x is 6 + x.
(ii) 3 more than a number y means y + 3.
(iii) One-third of a number x is $\frac{x}{3}$.
(iv) One-half of the sum of numbers x and y is $\frac{(x+y)}{2}$.
(v) Number y less than a number 7 means 7 $-$ y.
(vi) 7 taken away from x means x $-$ 7.
(vii) 2 less than the quotient of x by y is $\frac{x}{y}-2$.
(viii) 4 times x taken away from one-third of y is $\frac{y}{3}-4x$.
(ix) Quotient of x by 3 is multiplied by y means:

$\frac{x}{3}\times y=\frac{xy}{3}$
