Ava solved the problem 7.4 x 1.2 with partial products. these are the first 3 steps.

7.0 x 1.0 = 7
7.0 x 0.2 = 1.4
0.4 x 1.0 = 0.4

Ava's method of solving 7.4 x 1.2 using partial products is a great way to break down the multiplication into manageable parts.

To find the product of 7.4 and 1.2, she began by breaking the numbers down:

  1. Calculate 7.0 x 1.0:

    • \(7.0 \times 1.0 = 7\)
  2. Calculate 7.0 x 0.2:

    • \(7.0 \times 0.2 = 1.4\)
  3. Calculate 0.4 x 1.0:

    • \(0.4 \times 1.0 = 0.4\)

Now, we can combine these partial products to find the total:

  • Total = \(7 + 1.4 + 0.4\)

Now, let's add these three results together:

  1. \(7 + 1.4 = 8.4\)
  2. \(8.4 + 0.4 = 8.8\)

Thus, the product of 7.4 and 1.2 using partial products is:

7.4 x 1.2 = 8.88
