00:00:03.080 --> 00:00:19.840
Tick the two numbers that are equivalent to one-quarter: 0.25, 0.75, twenty-five hundredths, 0.5, or two-fifths.
00:00:19.840 --> 00:00:23.560
Let’s start with the first number, 0.25.
00:00:25.120 --> 00:00:31.040
The model shows one square divided into 100 smaller squares.
00:00:32.280 --> 00:00:37.280
Each square represents one hundredth.
00:00:37.280 --> 00:00:40.600
25 out of 100 squares have been shaded.
00:00:41.680 --> 00:00:46.320
And we’ve recalled this or write this as 0.25.
00:00:47.720 --> 00:00:53.720
Twenty-five hundredths is 0.25.
00:00:53.720 --> 00:00:57.320
We know that four times 25 equals 100.
00:00:57.920 --> 00:01:03.600
So four times 0.25 equals one.
00:01:03.600 --> 00:01:10.680
So one divided into four equal parts or quarters equals 0.25.
00:01:12.400 --> 00:01:15.880
We know that 0.25 is equivalent to a quarter.
00:01:16.960 --> 00:01:26.680
So 0.75 must be equivalent to three-quarters because it’s three times bigger than 0.25.
00:01:26.680 --> 00:01:30.160
So we don’t need to tick this number.
00:01:30.160 --> 00:01:35.720
We already know that we write twenty-five hundredths as 0.25.
00:01:37.280 --> 00:01:40.920
100 divided by four is 25.
00:01:41.680 --> 00:01:44.520
That means there are four 25s in 100.
00:01:45.680 --> 00:01:49.760
So twenty-five hundredths is equal to one-quarter.
00:01:51.480 --> 00:01:54.720
0.5 is equal to one-half.
00:01:56.080 --> 00:02:00.960
Two-fifths is not equal to one-quarter.
00:02:00.960 --> 00:02:04.320
These two models show two-fifths and one-quarters.
00:02:04.320 --> 00:02:08.520
And we can clearly see that they are not equal.
00:02:08.520 --> 00:02:16.800
The two numbers that are equivalent to one-quarter are 0.25 and twenty-five hundredths.
