1.5m to 40cm
=150cm to ______ cm
or 150:______
Lowest form =______
40,40
15:4
Given 1.5m to 40cm= 150cm to 40cm
150cm to 40cm=150:40
Lowest form of 150:40=150÷1040÷10=154 ( Divided by HCF of 150and40 which equals to 10)
Hence, lowest form of =150:40=15:4
Show that for each nautral number n, the fraction is in its lowestform.
