Explain the expression "a tenth". How do we represent a tenth using decimals? [1 MARK]
If a block of one unit is divided into 10 equal parts, then each part is 110(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×(110) = 0.5.
