In arithmetic, we have studied that the division sign

Thus, 20 divided by x is written as 20/x and x is divided by 3 is written as x/3. It should be noted that 1/3 of x or x is divided by 3 is also written as x/3

1. Write each one of the following phrases by using numbers, literals and signs of basic operations:

(i) Quotient of x by 3 is multiplied by y

We have, quotient of x by 3 = (x/3).(y)

= xy/3

(ii) 3 times x added to 7 by y

We have, 3 times x = 3x, and 7 by y = 7/y.

∴ 3 times x added to 7 by (divided) y = 3x + 7/y.

(iii) Quotient of x by 4 is added to z

We have, Quotient of x by 4 = x/4 + z

(i) Quotient of z by 6 is multiplied by y.

We have, Quotient of z by 6 = z/6

:. Quotient of z by 6 is multiplied by y means , z/6 x y = zy/6

(ii) Quotient of x by y added to the product of x and y

We have, Quotient of x by y = x/y, and product of x and y = xy

∴ Quotient of x by y added to the product of x and y = x/y + xy

(iii) 4 taken away from the quotient of x by 2y.

We have, Quotient of x by 2y = x/2y

∴ 4 taken away from the quotient of x by 2y = x/2y – 4
