Multiply decimals by whole numbers and perform divisions by non-zero whole numbers where the results are terminating decimals, with and without the use of digital technologies (ACMNA129)
Outcomes
-
Use mental strategies to multiply simple decimals by single-digit numbers, eg 3.5 x 2
Examples
-
Multiply decimals of up to three decimal places by whole numbers of up to two digits, with and without the use of digital technologies, eg 'I measured three desks. Each desk was 1.25 m in length, so the total length is 3 x 1.25 = 3.75 m'
Examples
-
Divide decimals by a one-digit whole number where the result is a terminating decimal, eg 5.25 / 5 = 1.05
Examples
-
Solve word problems involving the multiplication and division of decimals, including those involving money, eg determine the 'best buy' for different-sized cartons of cans of soft drink
