Factorising means to express a term as the product of its factors.

Multiplying with decimals

Maths

Pupils use their understanding of place value and fluency with decimals from this unit in order to extend this understanding to fractions.  In the future unit, pupils will be asked to compare and order both fractions and decimals and will assess when conversion is required.

The prior unit on factors, multiples, squares and cubes helped pupils build on their understanding that any positive integer can be expressed as a product of its factors. This skill is used here to explore multiplying and dividing with decimals.

Arithmetic procedures with integers and decimals

A __________ is the result of two or more numbers multiplied together.

Dividing by 1000 is equivalent to __________

Which of these is equivalent to $$4.56\times2.3$$?

Using your knowledge on identifying a reasonable answer and without working out, match the calculation to the correct answer.

A {{ }} is a term which exactly divides another term.

Match the multiplication of these integers with their answers

Complete the calculation:  $$6\times$$ {{ }} $$= 600$$

Divide 1 into 10 equal parts. What does each part represent as a decimal?

Divide 1 into 100 equal parts. What does each part represent as a decimal?

Without using a calculator, work out: $$2.4+1.28+0.3+0.13=$$ {{ }}
