They told us how much Victoria used in fractions.
1. Add up the total amount she used.
2/5 + 3/10 = total amount used

Make both denominators the same.
2/5(2/2) + 3/10 = total amount used
4/10 + 3/10 = total amount used
7/10 = total amount used

2. Find out how much is left.
If she used 7/10 of the total package she has 3/10 left, because 10/10 - 7/10 = 3/10.

3. Find the weight of 3/10 of the package

The whole package, 10/10, weighs 2 pounds,
so each 1/10 of package = 2lbs/10 = 0.2 lbs

Now we know we have 3/10 left, so multiply 0.2 by 3 which equals 0.6 pounds.
Victoria has 0.6 pounds of flour left.

Hope this answers your question, and May the Force Be With You!

Answer : The weight of the package of flour that she left is, 0.84 pounds.

Step-by-step explanation :

As we are given that the Victoria has a 2 pound package of flour.

First we have to calculate the amount of flour use to make a pizza.

Amount of use to make a pizza =
(2)/(5)* 2\text{ pounds}=(4)/(5)\text{ pounds}

Now we have to calculate the amount of flour use to make a bread.

She then uses 3/10 of the remaining flour to make bread. That means,

Remaining flour to make bread =
1-(2)/(5)=(3)/(5)

Fraction of flour use to make a bread =
(3)/(10)* (3)/(5)

Amount of use to make a bread =
(3)/(10)* (3)/(5)* 2\text{ pounds}=(9)/(25)\text{ pounds}

Now we have to calculate the weight of the package of flour that she has left.

Weight of the package of flour that she has left = Total amount of flour - (Sum of flour use to make a pizza and bread)

Weight of the package of flour that she has left =
2-((4)/(5)+(9)/(25)) pounds

Weight of the package of flour that she has left =
2-(4)/(5)-(9)/(25) pounds

Weight of the package of flour that she has left =
(21)/(25) pounds

Weight of the package of flour that she has left = 0.84 pounds

Thus, the weight of the package of flour that she left is, 0.84 pounds.
