Extension -
Investigate the flag design of Panama and Hungary and work out what fraction of the flag each colour is. |
Flag Design
The government of Terraman decided that the country needed a new flag. They surveyed the citizens of Terraman about preferred colours and discovered that 3/8 preferred red, 1/4 preferred blue, 1/8 preferred green and 1/4 preferred yellow.
It was decided to incorporate all colours in this new flag with 3/8 of the flag red, 1/4 blue, 1/8 green and 1/4 yellow. Things to consider... Would folding paper help? Is there more than one possible design for this flag? Use graph paper to assist you. |
Fractions, Decimals and Percentages
Year 5 Year 5 Compare and order common unit fractions and locate and represent them on a number line (ACMNA102)
Year 6 Compare fractions with related denominators and locate and represent them on a number line (ACMNA125)
Year 6 Compare fractions with related denominators and locate and represent them on a number line (ACMNA125)
Why is it Important?
Before we can add or subtract fractions, the fractions need to have a common denominator
Iin other words the denominators must be the same.
Making The Denominators the Same
To make the denominators the same we can:
Multiply top and bottom of each fraction by the denominator of the other.
