00:00:01.722 --> 00:00:03.332
Fill in the missing value.
00:00:03.952 --> 00:00:10.272
0.51 plus nine twentieths is equal to blank percent.
00:00:11.652 --> 00:00:18.492
Normally, with a question like this, we would look to turn both numbers into either decimals or fractions.
00:00:19.092 --> 00:00:26.892
However, as we’re looking to give our answer as a percentage, it is worth turning both of them into percentages first.
00:00:27.932 --> 00:00:33.902
We want to convert 0.51 and nine twentieths into percentages.
00:00:34.692 --> 00:00:38.062
The word “percent” means out of 100.
00:00:39.042 --> 00:00:45.012
We, therefore, need to find an equivalent fraction to nine twentieths that is over 100.
00:00:45.882 --> 00:00:49.412
20 multiplied by five is equal to 100.
00:00:50.692 --> 00:00:56.222
As we have multiplied the denominator by five, we need to multiply the numerator by five.
00:00:57.062 --> 00:01:00.122
Nine times five is equal to 45.
00:01:01.312 --> 00:01:10.342
As 45 over 100 is the same as 45 percent, then nine over 20 is also equal to 45 percent.
00:01:11.562 --> 00:01:16.902
To convert any decimal into a percentage, we need to multiply by 100.
00:01:17.792 --> 00:01:22.442
0.51 multiplied by 100 is equal to 51.
00:01:22.802 --> 00:01:26.122
Therefore, this is equal to 51 percent.
00:01:27.622 --> 00:01:33.182
Our calculation becomes 51 percent plus 45 percent.
00:01:34.152 --> 00:01:37.812
51 plus 45 is equal to 96.
00:01:38.152 --> 00:01:44.322
Therefore, 0.51 plus nine twentieths is equal to 96 percent.
