Calculate seven and seventeen hundredths minus six and twenty-three hundredths.
00:00:10.420 --> 00:00:23.640
The key to solving this problem is to make sure we line up the decimals, seven and seventeen hundredths minus six and twenty-three hundredths.
00:00:24.150 --> 00:00:26.600
The hundredths places are lined up.
00:00:27.060 --> 00:00:29.500
The tenths places are lined up.
00:00:30.000 --> 00:00:31.990
And the ones places are lined up.
00:00:32.850 --> 00:00:34.390
So we’re ready to subtract.
00:00:35.370 --> 00:00:40.530
Starting all the way on the right, seven minus three equals four.
00:00:41.590 --> 00:00:45.670
One minus two, well we can’t solve one minus two.
00:00:46.350 --> 00:00:48.940
We need to borrow from the ones place.
00:00:49.530 --> 00:00:56.800
If we take away one of the ones, we can turn our tenths place into eleven tenths.
00:00:57.640 --> 00:01:02.260
And then we can say 11 minus two equals nine.
00:01:03.070 --> 00:01:04.430
Bring down our decimal.
00:01:04.430 --> 00:01:06.350
Make sure it stays in line.
00:01:06.880 --> 00:01:10.220
Six minus six equals zero.
00:01:11.520 --> 00:01:20.380
Seven and seventeen hundredths minus six and twenty-three hundredths equals zero and ninety-four hundredths.
