11/50 a % is out of a hundred. so fifty 5% is like fifty 5/a hundred . then you definitely simplify it by utilising looking a straightforward diverse. 5 could be divisible by utilising the two fifty 5 and a hundred, so which you divide them, making the respond be 11/50
If you have 0s both in numerator and denominator, you can cancel them.
it means, you have 21/45 left in you.
In changing it lowest tern, you have to think of a factors of both numbers and you always consider the factors of the smaller value and that is 21. What are the factors of 21? 3, 7 and 21
210/450 Since both numbers have a 0 at the end you can just take them off or divide by 10 which does the same thing and you'll end up with:
21/45 Now just find what both numbers are divisible by. You can divide them both by 3 and you'll end up with:
7/15 and since you can't divide them both by the same number anymore thats your answer.
Both the numerator and denominator are multiples of 3. Therefore, divide top and bottom by 3: 7/15
Answer: 7/15
You can also check your answers by using a calculator after performing simplification. I strongly suggest that you'll train yourself to perform such operations as fast as you can without using a calculator. This will aid you in performing mental calculations much faster in exams. Good luck:)
