Answer:

The steps are shown below:

Step-by-step explanation:

We can draw the area model for 2-digit by 2-digit multiplication by using the following steps:

Step 1: First write the multiplicands in expanded form.

For example: 26 as 20 and 6, and 36 as 30 and 6.

Step 2: Now, Draw a 2 × 2 grid, and write the terms of one of the multiplicands on the top of the grid. One on the top of each cell.

Step 3: Write the terms of the other multiplicand on the left of grid.

Step 4: Write the product of ones and tens in respective cell.

For example: 26×36

20 6

30| 600 180

6 | 120 36

Now add them: 600+180+120+36=936

Taylor says that 40 percent of 50 is the same amount as 50 percent of 40 is she correct

Answers

If you would like to know if Taylor is correct, you can calculate this using the following steps:

40% of 50 = 40% * 50 = 40/100 * 50 = 20
50% of 40 = 50% * 40 = 50/100 * 40 = 20

Result: Taylor is correct, because 40% of 50 equals to 50% of 40.

She is correct 40% is 50 because the answer is 125
