The ratio of 21.5: 20.5 is same as?Options2:16: 13:23:1

The ratio of 21.5 to 20.5 can be simplified by dividing both numbers by their greatest common divisor. In this case, that would be 1. So, the simplified ratio is 21.5/1 : 20.5/1, which simplifies to 21.5 : 20.5.

Now, let's compare this simplified ratio to the options given:

1. 2:16 - This ratio simplifies to 1:8, which is not the same as 21.5 : 20.5.
2. 13:23 - This ratio is already in its simplest form and is not the same as 21.5 : 20.5.
3. 1:1 - This ratio is also in its simplest form and is not the same as 21.5 : 20.5.

Therefore, none of the options given are the same as the ratio of 21.5 : 20.5.

To find out if the ratio 21.5:20.5 is the same as any of the given options, we first need to simplify the ratio to its simplest form.

Step 1: Simplify the ratio 21.5:20.5 To simplify a ratio, we divide both numbers by their greatest common divisor (GCD). In this case, the GCD of 21.5 and 20.5 is 1. So, we divide both numbers by 1.

21.5 ÷ 1 = 21.5 20.5 ÷ 1 = 20.5

So, the simplified ratio is 21.5:20.5.

Step 2: Compare the simplified ratio with the given options Now, we compare this simplified ratio with the given options.

Option 1: 2:16 This ratio can be simplified to 1:8, which is not the same as 21.5:20.5.

Option 2: 13:23 This ratio is already in its simplest form and is not the same as 21.5:20.5.

Option 3: 1 This is not a ratio, so it cannot be the same as 21.5:20.5.

Therefore, the ratio 21.5:20.5 is not the same as any of the given options.
