Briahna mixes red and silver glitter for an art project. She has 20 packets of red glitter and 30 packets of silver glitter when she starts.
She wants the same mixture every time, so the amounts of red and silver glitter
must always be proportional to the original mixture.
For the first batch, she mixes 5 packets of red glitter and 10 packets of silver
glitter.
For the second batch, she mixes 8 packets of red glitter and 16 packets of silver
glitter.
Fill in the blanks to find the highest number of packets of each color
that Briahna can combine to make the same glitter mix in a third
batch.
