Complete the sentences to explain Anna’s work.
In the first step, Anna solved 8 × 3.
In the second step, Anna solved 20 × 3.
20 × 3 is equal to ____ which is equivalent to ____ tens.
Then, Anna added the 2 tens that were regrouped to get ____ tens.
In the first step, Anna solved 8 × 3, which equals 24.
In the second step, Anna solved 20 × 3, which equals 60, which is equivalent to 6 tens.
Then, Anna added the 2 tens that were regrouped to get 8 tens.
### Explanation:
Anna breaks down the multiplication of 28 × 13 into smaller parts. First, she multiplies the units (8 from 28 and 3 from 13) and finds 24. Then, she multiplies the tens (20 from 28 and 3 from 13) to find 60, which is made up of 6 tens. Finally, when she adds the 2 tens from the 24 (which she regrouped), she gets a total of 8 tens. This step-by-step method helps in organizing her calculations effectively.
