To represent something means to show something in a different way.

Explain how to multiply two non-unit fractions

Maths

In this unit pupils will learn how to multiply 2 unit fractions and 2 non-unit fractions. They will learn how to divide a unit fraction and a non-unit fraction by a whole number. In the future unit pupils will explain what percent means and how to represent a percentage in different ways. They will learn how to convert percentages to decimals and fractions and solve conversion problems.

 In the prior unit pupils used fraction sense to fraction addition, subtraction and comparison, explaining how to compare pairs of non-related fractions by converting to common denominators or using fraction sense. In this unit pupils will learn how to multiply 2 unit fractions and 2 non-unit fractions. They will learn how to divide a unit fraction and a non-unit fraction by a whole number. 

Multiplication and division of fractions

$$ {2} \over {5}$$ × $$ {1} \over {4}$$ = $$ {2} \over {20}$$

$$ {2} \over {5}$$ × $$ {1} \over {3}$$ = $$ {2} \over {15}$$

$$ {2} \over {3}$$ × $$ {1} \over {4}$$ = $$ {2} \over {12}$$

$$ {2} \over {5}$$ + $$ {1} \over {4}$$ = $$ {3} \over {9}$$

Tick the equation that matches this image.

$$ {3} \over {4}$$ × $$ {1} \over {4}$$ = $$ {3} \over {16}$$

$$ {3} \over {4}$$ × $$ {1} \over {5}$$ = $$ {3} \over {20}$$

$$ {3} \over {4}$$ × $$ {1} \over {5}$$ = $$ {3} \over {9}$$

$$ {3} \over {4}$$ + $$ {1} \over {5}$$ = $$ {3} \over {9}$$

Tick the product of: $$ {3} \over {5}$$ × $$ {1} \over {6}$$
