To determine who is correct, let's evaluate both statements:

Kate said 10 multiplied by 4 equals 40.
John said 20 multiplied by 4 equals 40.

We can calculate the correct answer for each statement by actually performing the multiplication.

For Kate's statement, we calculate 10 multiplied by 4 which gives us 40.

For John's statement, we calculate 20 multiplied by 4 which gives us 80, not 40.

Based on our calculations, Kate's statement is correct. The correct answer is 10 multiplied by 4 equals 40.
