00:00:00.640 --> 00:00:06.600
Fill in the blanks in the given figure such that the corresponding numbers in the two rows are proportional.
00:00:08.040 --> 00:00:13.720
In order for the numbers in the two rows to be proportional, each pair of values must be in the same ratio.
00:00:14.480 --> 00:00:18.360
We can use the pair of values that have both been given to us in order to work out what this ratio is.
00:00:19.600 --> 00:00:26.080
The ratio of the bottom row divided by the top is 60 divided by six.
00:00:26.560 --> 00:00:27.680
This is equal to 10.
00:00:28.600 --> 00:00:36.400
This means that numbers in the bottom row of the table are 10 times as large as the corresponding number in the top row.
00:00:37.320 --> 00:00:44.400
Equivalently, numbers in the top row are 10 times smaller than their pair in the bottom row.
00:00:45.480 --> 00:00:48.560
We can fill in the two numbers in the circles.
00:00:49.360 --> 00:00:56.560
To work out a number in the bottom row from its pair in the top, we need to multiply by 10.
00:00:57.600 --> 00:01:05.400
To work out a number in the top row from its pair in the bottom, we need to divide by 10.
00:01:06.600 --> 00:01:09.720
Next, let’s calculate the missing number in the bottom row.
00:01:10.320 --> 00:01:15.360
In order to calculate this, we need to multiply its pair in the top row by 10.
00:01:16.000 --> 00:01:21.000
This number is equal to 11 multiplied by 10, which is 110.
00:01:21.920 --> 00:01:26.640
Finally, we calculate the last missing number, the missing number in the top row.
00:01:27.320 --> 00:01:32.240
To calculate it, we divide its corresponding number in the bottom row by 10.
00:01:33.440 --> 00:01:37.080
It’s equal to 190 divided by 10, which is 19.
00:01:37.680 --> 00:01:47.280
The four missing numbers in the figure from left to right are 10, 110, 19, 10.
