Answer: Decimals are accualy simular to fractions. Decimals are not 1 whole. So how can you write a part? You can write decimals as a fraction if you prefer, they are both simular because, lets say you have 10 pieces of Lego. And you have 5 green, and 5 purple. But, the answer is saying, how many pieces of Lego are purple. We can write this as 0.5 or 5/10 of the Lego are purple. Chart below! :)
