Laura painted her room with pink paint that was made by mixing paint at a ratio of 5 parts white paint to 2 parts red paint. Wil
lakkis [162]

Answer:

No

Step-by-step explanation:

Laura painted her room with pink paint that was made by mixing paint at a ratio of 5 parts white paint to 2 parts red paint.

Suppose Laura has 15 parts of white paint. This is thrice the amount Laura needs (because 15:5=3), so she has to have

2\cdot 3=6

parts of red paint.

Hence, if Laura combines 15 parts white and 3 parts red paint, then she will not create the same shade of pink as she used.
