Estimating and Calculating Homework

We were given two questions. They were 46 x 4.5 and 64 x 4.5.
Here is how we did it.
46 x 4.5
We started by rounding the number 4.5 to 5. Then we multiplied or calculated 46 x 5= 230 then we had to put the decimal back in, we moved it one place value over, so now the answer is 23.0.There is the estimation.
The next one was 64 x 4.5.
Here is how we did it.
We rounded 4.5 to 5
then multiplied or calculated it by 64, and got 320, again we had to put the decimal back in so we moved it over one place value, so now the answer is 32.0.

  13. Good job Breanna. You did good. But you should add a picture and you don't have to add the zero at the end of 23.0 and 32.0.
