What I would do is to times 9 x 5 = 45

Then, I would times 1/2 x 5 = 2 1/2

Then 45 + 2 1/2 = 47 1/2

You can use estimation by multiplying 9 and 1/2 by 5 and adding their answers to get your answer. Happy to help! c:

You write it as 46 divide by 1058. 46 x 2 is the closest you will get to 100. 46 x 2 is 92. put it in and you have 138 left. multiply 46 x 3 and you will get 138. amswer is 23. remember to bring down the next number whwn dividing
