Question

Duncan had 3.8 gallons of paint and used 1.89 gallons for a poster. How much paint did Duncan have left after painting the posture.

Answer 1

1.91

Explanation:

Duncan had 3.8 and used 1.89 obviously we can't subtract right now so we have to add a 0 to 3.8 so it would 3.80 - 1.89 = 1.91

Answer 2

1.91 gallons left
3.8-1.89= 1.91 gallons
