Jacob has a new TV set with a size of 24 inches.

00:00:06.380 --> 00:00:08.410
Find the size in centimeters.

00:00:08.510 --> 00:00:12.730
Hint: 12 inches is approximately 30 centimeters.

00:00:13.280 --> 00:00:15.980
So let’s imagine we have Jacob’s TV set.

00:00:16.190 --> 00:00:18.030
We’re told it’s 24 inches.

00:00:18.030 --> 00:00:24.760
And as for TV sets, that’s usually the length of the diagonal, we need to find the equivalent value in centimeters.

00:00:25.280 --> 00:00:30.730
We’re given the conversion here that 12 inches is approximately 30 centimeters.

00:00:30.970 --> 00:00:33.670
In this case, however, we don’t have 12 inches.

00:00:33.840 --> 00:00:35.410
We have 24 inches.

00:00:35.670 --> 00:00:41.230
So we need to establish how we go from 12 to 24 by multiplying or dividing.

00:00:41.550 --> 00:00:46.170
Well, if we double 12 or multiply it by two, we’ll get to 24.

00:00:46.510 --> 00:00:52.290
Therefore, we have to do the same on the other side with our value of 30 centimeters.

00:00:52.690 --> 00:00:56.370
30 multiplied by two gives us 60 centimeters.

00:00:56.510 --> 00:00:59.600
And that would be our answer for 12 inches.

00:00:59.910 --> 00:01:05.800
In this question, we were given the hint of a conversion between 12 inches and 30 centimeters.

00:01:06.070 --> 00:01:10.070
Usually, in exam questions, we’ll need to recall a conversion.

00:01:10.280 --> 00:01:13.790
For example, one inch is 2.5 centimeters.

00:01:14.040 --> 00:01:24.660
In this case, we would have multiplied both sides of the conversion one inch equals 2.5 centimeters by 24, which would also have given us an answer of 60 centimeters.
