Aparticular 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?

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
