Step 1

Since baker wants that each pie contains 3.5 cups of blueberries, to calculate how many cups will she need if sshe is going to make 24 pies, we have to find the next prodduct:

$24\times 3.5=?$

1) Multiply these numbers as if they were both whole numbers, ignoring the decimal point

$$\begin{array}{cccc}& & 2& 4\\ \times & & 3.& 5\\ & 1& 2& 0& \to & 1& \text{partial product,}& 24\times 5\\ & 7& 2& 0& \to & 2& \text{partial product,}& 24\times 3\end{array}$$

2) Add partial products

$$\begin{array}{cccc}& & 2& 4\\ \times & & 3.& 5\\ & 1& 2& 0\\ +& 7& 2& 0\\ & 8& 4& 0\end{array}$$

3) Compensate by placing the decimal point in the product

$$\begin{array}{cccc}& & 2& 4\\ \times & & 3.& 5& \to & \text{one decimal digit}\\ & 1& 2& 0\\ +& 7& 2& 0\\ & 8& 4& 0& \to & \text{one decimal digit}\end{array}$$

Therefore,

$24\times 3.5=84$

The baker will need 84 cups of blueberries.

Step 1

$1\text{}\text{pie}=3.5\text{}\text{cups of blueberries}$

$24\text{}\text{pies}=?\text{}\text{blueberries}$

Since you already know how many blueberries are needed for one pie, now to find how many blueberries are needed for 24 pies, multiply 24 by 3.5:

$24\cdot 3.5=84$

Since you already know how many blueberries are needed for one pie, now to find how many blueberries are needed for 24 pies, multiply 24 by 3.5:
