Hope this helps
Bye !!

210 / 450
= (2 * 3 * 5 * 7) / (2 * 3 * 3 * 5 * 5)
= (7) / (3 * 5)
= 7 / 15

= 210/450
= (210/30)/(450/30)
= 7/15

Answer: 7/15

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

Hi, This is simple as this.

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


you cant divide 45 by 21
You cant divide 45 by 7


The only value remaining is 3.

You can divide 3 to both of them

so, 21/45 is

= 7/15

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.

Original fraction: 210/450

Divide by 10 top and bottom: 21/45

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:)

210/450 = 21/45 = 7/15
