Question

A particular shade of paint is made by mixing 5 parts red paint with 7 parts blue paint. To make this shade, Shannon mixed 12 quarts of blue paint with 8 quarts of red paint. Did Shannon mix the correct shade?

Answer 1

If you look closely you will see that its two fractions. So to answer the question you have to see if 5/7 is equal to 8/12. So do 12 times 7 to make the denominators equal then make the numerators proportional by doing 8 times 7 and 5 times 12. You get 60/84 = 56/84 so because they are equivalent she didnt mix the paints correctly
