Answer: 51g : 26g
Explanation:
First, we need to find out what "the rest" is, since that is sugar. We will subtract the grams of strawberries and blackberries from the total grams of sugar.
100g - 23g - 51g = 26 g
Now, the ratio asks for blackberries to sugar.
Blackberries : Sugar
51g : 26g
Lastly, it asks for the simplest form. This ratio is already in the simplest form.
51g : 26g
