00:00:01.020 --> 00:00:03.660
Isabella has some nickels in her purse.
00:00:04.240 --> 00:00:08.320
She wants to swap them with her mother for a quarter and a dime.
00:00:08.710 --> 00:00:11.040
How many nickels does she need to give?
00:00:13.060 --> 00:00:15.460
Isabella has some nickels.
00:00:16.850 --> 00:00:19.600
She wants a quarter and a dime.
00:00:21.350 --> 00:00:28.610
We need to know how many nickels will equal the same value as one quarter and one dime.
00:00:29.940 --> 00:00:33.150
Here, we have a quarter and a dime.
00:00:34.740 --> 00:00:40.590
We need to ask the question; how much is one quarter and one dime worth?
00:00:42.220 --> 00:00:45.210
One quarter is worth 25 cents.
00:00:46.930 --> 00:00:49.340
And one dime is worth 10 cents.
00:00:51.230 --> 00:00:55.220
We can add 25 cents plus 10 cents.
00:00:56.150 --> 00:00:58.780
That equals 35 cents.
00:01:00.410 --> 00:01:08.650
To solve this question, we need to know how many nickels would we need to equal 35 cents.
00:01:10.190 --> 00:01:13.820
Every nickel is worth five cents.
00:01:15.470 --> 00:01:19.210
If we had two nickels, we would have 10 cents.
00:01:20.670 --> 00:01:24.610
Let’s count by fives to see if we have enough nickels now.
00:01:25.660 --> 00:01:33.950
Five, 10, 15, 20, 25, 30.
00:01:35.390 --> 00:01:37.780
So far, we have 30 cents.
00:01:38.060 --> 00:01:40.570
Six nickels equals 30 cents.
00:01:40.860 --> 00:01:42.270
That’s still not enough.
00:01:43.710 --> 00:01:53.310
If we add a seventh nickel, we would say 30 cents plus five equals 35 cents.
00:01:55.110 --> 00:02:01.860
It takes seven nickels to equal the same amount as one quarter and one dime.
00:02:03.650 --> 00:02:09.710
It takes seven nickels to equal the same value as one quarter and one dime.
00:02:10.270 --> 00:02:17.930
If Isabella wants to swap her mother for one quarter and one dime, she will need seven nickels.
