Question

Trying to help my daughter with a question for her maths that has got me stuck...wish I was better at maths!

Convert the fraction 27/50 into decimal

Could someone please help me with this question.

Answer 1

Remember that our numeration system has basis $10$ so $$\frac{27}{50}=\frac{27\times 2}{50\times 2}=\frac{54}{100}=0.54$$

Answer 2

$\frac{27}{50}=\frac{27*2}{50*2}=\frac{54}{100}=0.54$
