Answer:
4950
Step-by-step explanation:
The smallest number when rounded to the nearest 100 that becomes 5000 should be between the range of 4950 and 4999.
To the round any figure to the nearest hundred, the of the number should be considered. If the number ranges from 1 to 49, it should be rounded to previous hundred, but if the number is between the range of 50 to 99, it should be rounded to the next 100.
Therefore the smallest number when rounded to the nearest 100 that becomes 5000 is 4950
Answer:
Step-by-step explanation:
- First, let's go over the <em>distributive property </em>in math. When you have any expression within a parenthesis being multiplied by any expression outside a parenthesis, you are distributing the values outside onto the values inside, like so:
⇒
- Hopefully this helps you break down how distribution works, but if you're still having trouble comprehending it, looking at examples will help. Now, back to the problem. Let's try this idea of distribution on the left side of the equation.
- Hopefully you could follow this math, but if not, there are plenty of materials online and in books on this. Be sure to look at those if you still have trouble.
- Now that we have done all the multiplication we can on the left side and only addition and subtraction remain, we can get rid of the parentheses.
- Now let's do distribution for the other side as well. Doing this will help us easily isolate
on one side after.
- Now, using addition and subtraction, let's move all our
- In case you're confused by the last step there, what I did was divide both sides by the coefficient in front of our
- The fraction
is technically correct, but it isn't simplified.
