While walking in his backyard, cooper found a rock. He decided to investigate what the inside of the rock looked like, so he use
d a hammer and broke thr rock into two parts. The entire rock before it was broken had a mass of 20 grams. After he broke the rock the smaller piece had a mass of 5 grams. What must the mass of the larger piece of rock be? I need the answer ASAP!!!
You have 2 parts of the rock. If the whole rock is equal to about 20grams, and one part of the rock is 5 then you just see how much grams you need to get to 20.
