Question

Explain the expression "a tenth". How do we represent a tenth using decimals? [1 MARK]

Answer 1

If a block of one unit is divided into 10 equal parts, then each part is $\frac{1}{10}$(one-tenth) of the unit. It is written as 0.1 in decimal representation. The dot denotes the decimal point.

For example, a tenth​​​​​ of 5 = 5$\times$($\frac{1}{10}$) = 0.5.
