To find out how many blocks Zoe placed on the scale, we can use the formula that relates weight, number of blocks, and weight of each block.
Let:
- \( w \) be the weight of each block (0.8 ounces),
- \( n \) be the number of blocks,
- The total weight of all blocks is given as 12.8 ounces.
We can set up the equation:
\[
w \times n = \text{total weight}
\]
Substituting the known values:
\[
0.8 \times n = 12.8
\]
To find \( n \), we can solve for it by dividing both sides of the equation by 0.8:
\[
n = \frac{12.8}{0.8}
\]
Performing the division, we get:
\[
n = 16
\]
Therefore, Zoe placed **16 blocks** on the scale.
