Which fraction is easier to convert into a decimal?

11/18 or 43/50, explain

Answers

43/50 is easier because 50 is half of 100

Watch this

43/50. Since 50 is HALF of 100 so we multiply 2 by 50 which is 100. But since we multiplied by 2 for the denominator we have to do the same for the numerator so 43 x 2 is equal to 86.

So we get 86/100 which is 0.86

43/50 decimal 0.87

It's easier to turn into a decimal because both are bigger numbers and and closer to each other so it would be easier to divide
