Here are the ingredients for chocolate ice cream.
00:00:06.360 --> 00:00:18.400
Cream: 400 millilitres, milk: 500 millilitres, egg yolks: four, chocolate: 120 grams, sugar: 100 grams.
00:00:19.920 --> 00:00:24.920
Stefan only has 300 millilitres of cream to make chocolate ice cream.
00:00:25.720 --> 00:00:28.440
How much chocolate should he use in grams?
00:00:30.320 --> 00:00:34.280
We know that Stefan only has 300 millilitres of cream.
00:00:35.680 --> 00:00:39.000
And the recipe needs 400 millilitres.
00:00:40.200 --> 00:00:46.120
So Stefan has 300 out of the 400 millilitres that he needs.
00:00:47.720 --> 00:00:57.680
If we divide both of these amounts by 100, we can see that three hundred four hundredths is equal to three-quarters.
00:00:59.800 --> 00:01:07.760
So to calculate how much chocolate Stefan needs, we need to work out three-quarters of 120 grams.
00:01:09.080 --> 00:01:17.080
We can find a quarter of 120 grams by dividing 120 by four, which is 30.
00:01:18.720 --> 00:01:24.920
And then to find three-quarters, we multiply 30 by three to give us our answer, 90.
00:01:26.120 --> 00:01:29.160
And the question tells us to write our answer in grams.
00:01:30.640 --> 00:01:35.280
Stefan needs 90 grams of chocolate to make his chocolate ice cream.
