Question

Mathilde has 30 pints of green paint. She uses 3/5 of it to paint a landscape and 3/10 of it while painting a clover. She decides she that, for her next painting, she will need 16 pints or green paint. How much more green paint will she need to buy?

Answer 1

Answer: 13 pints

Explanation:

she used 27 pints at first (9/10 of the 30)
