Question

12. Lydia is painting flower vases. Each vase takes 3⁄16 of a quart of paint. She has 21⁄2 quarts of paint. How many flower vases can she paint? A. 131⁄3 B. 3111⁄16 C. 151⁄6 D. 101⁄2

Answer 1

As we may be dividing fractions...
$\frac{21}{2} \div \frac{3}{16} = \frac{21}{2} \times \frac{16}{3} = \frac{7}{1} \times \frac{8}{1} = 56$
