Jaleah has a 2-pound package of flour. She uses 2/5 of the flour to make a pizza. She then uses 3/10 of the remaining flour to make bread. Find the weight of the package of flour that she has left. Express you answer as a decimal.
0.4 * 2 = 0.8 pounds
0.3 * 1.2 = 0.36 pounds left
2 - 2/5*(2) = 10/5 - 4/5 = 6/5 = 1.2 Lbs. remaining.
1.2 - 3/10*(1.2) = 1.2 - 0.36 = 0.84 Lbs. remaining.
To find the weight of the package of flour that Jaleah has left, we need to subtract the weights of the flour used to make the pizza and the bread from the original weight of the package.
Jaleah used 2/5 of the flour to make the pizza. To find how much flour she used, we multiply the fraction by the weight of the package:
2/5 * 2 pounds = 4/5 of a pound
After making the pizza, Jaleah has 2 - 4/5 = 10/5 - 4/5 = 6/5 pounds of flour remaining.
Next, Jaleah uses 3/10 of the remaining flour to make bread. To find how much flour she used, we multiply the fraction by the remaining weight:
3/10 * (6/5 pounds) = 18/50 pounds
So, the weight of the package of flour that Jaleah has left is:
(6/5 pounds) - (18/50 pounds) = (30/25 pounds) - (18/50 pounds) = 30/25 - 18/50 = 60/50 - 18/50 = 42/50 = 0.84 pounds
Therefore, Jaleah has 0.84 pounds of flour left in the package.
