Question

Write the expressions for each of the following using brackets.
(a) Four multiplied by the sum of nine and two.
(b) Divide the difference of eighteen and six by four.
(c) Forty five divided by three times the sum of three and two.

Answer 1

a) four multiplied by the sum of nine and two
        4x(9+2)
b) Divide the difference of eighteen and six by four
         (18-6) / 4
c) 45 /3(3+2)

Answer 2

Answer:

(a) Four multiplied by the sum of nine and two.

Answer:  4 (9+2)

b) Divide the difference of eighteen and six by four.

The difference of 18 and 6 is written as 18-6 and it is then divided by four. Hence, the answer will be $\frac {(18-6)}{4}$

Answer:  $\frac {(18-6)}{4}$

(c) Forty five divided by three times the sum of three and two.

The numerator is explicitly given as 45 while the denominator had some expressions

Denominator = three times the sum of three and two = 3 (sum of three and two) = 3 (3+2).

Hence, the answer will be $\frac {45}{(3(3+2)}$

Answer: $\frac {45}{(3(3+2)}$
