Answer:
Its 8
Step-by-step explanation:
I know this because 8 is the only number they give you the other numbers they dont suply. Ps dont use my spelling and you might want to come up with a better answer. good luck
Since 89 is much smaller than 4731, your answer will be a small decimal fraction.
4731 is your divisor. Convert your dividend, 89, into a mixed decimal decimal number: 89.000000 ....
Now divide 89.000000 ... by 4731. 4731 goes into 8900 twice. So the first digit of your answer must be 2. Can you finish this? Show your work, please.
