You're welcome.
To use the fact that 11 multiplied by 5 equals 55 to solve 11 multiplied by 6, you can follow a simple pattern.
First, observe that multiplying any number by 10 is the same as adding a zero at the end. Therefore, expanding 11 multiplied by 5 as 11 multiplied by 10 and then dividing the result by 2 gives us 55.
Now, to find 11 multiplied by 6, you can follow a similar pattern. Multiply 11 by 10 to get 110, and then divide the result by 2 to get the answer.
So, 11 multiplied by 6 equals 110 divided by 2, which gives us 55.
