can you please do it in a way i will understand it?
i tried dividing 90 with 135 instead and i got 1.5 after adding the decimal mark where it was?
Hello,
I think this method is probably not what you're after, but you could use the idea of equivalent fraction:
$\displaystyle 13.5 \div 90 = \dfrac {13.5}{90}$
$\displaystyle \dfrac {13.5}{90} = \dfrac{27}{180}$
$\displaystyle \dfrac {27}{180} = \dfrac{3}{20}$
$\displaystyle \dfrac {3}{20} = \dfrac{15}{100}$
$\displaystyle \dfrac {15}{100} = 0.15$
