00:00:00.000 --> 00:00:05.920
Two decimal numbers add together to equal one.
00:00:06.600 --> 00:00:09.520
One of the numbers is 0.007.
00:00:09.960 --> 00:00:11.200
What is the other number?
00:00:13.200 --> 00:00:18.600
So we know that 0.007 plus the missing number equals one.
00:00:20.160 --> 00:00:29.720
We could use the inverse to help calculate the answer: one subtract 0.007 equals the missing number.
00:00:32.040 --> 00:00:36.080
The seven digit represents seven thousandths.
00:00:37.560 --> 00:00:43.240
And we can think of one whole as a thousand thousandths.
00:00:43.880 --> 00:01:01.240
So we need to subtract seven thousandths from a thousand thousandths, which leaves us with nine hundred and ninety-three thousandths, which we would write as 0.993 in decimal form.
00:01:03.160 --> 00:01:11.120
The number which we add to 0.007 to make one is 0.993.
