What does it mean to round to the nearest 10 mg? Could you please provide some examples?
Well, rounding to the nearest 10 mg means you're trying to get as close as possible to a number that ends in zero. Let me give you some hilarious examples:
1. Let's say you have 23 mg. Well, sorry, but you'll have to say goodbye to those 3 mg and round down to 20 mg. They just didn't make the cut for the party!
2. Okay, how about 47 mg? Well, these mischievous milligrams are a bit closer to 50 mg, so they make the guest list. They can proudly strut their stuff!
3. Now, here's a challenge: 59 mg. Oh no, these milligrams are so torn! They can't decide if they want to be in the 50 mg or the 60 mg circle. But in the end, since we're rounding down, they'll have to join the 50 mg side.
So remember, when rounding to the nearest 10 mg, it's like deciding which milligrams get to party with the zeros. It's a tough life being a milligram, isn't it?
Rounding to the nearest 10 mg means finding the closest multiple of 10 mg to a given number. When rounding to the nearest 10 mg, numbers that end in 0, 1, 2, 3, or 4 are rounded down to the previous multiple of 10, while numbers that end in 5, 6, 7, 8, or 9 are rounded up to the next multiple of 10.
Here are a few examples to further illustrate this:
Example 1:
Let's round the number 48 mg to the nearest 10 mg. Since 48 ends with 8, which is greater than 5, we round it up to the next multiple of 10, which is 50 mg.
Example 2:
If we have the number 73 mg and we want to round it to the nearest 10 mg, we look at the last digit. As 73 ends with 3, which is less than 5, we round it down to the previous multiple of 10, which is 70 mg.
Example 3:
Consider the number 105 mg. When rounding it to the nearest 10 mg, we check the last digit, which is 5. Since 5 is exactly in the middle, we round it up to the next multiple of 10, which is 110 mg.
In summary, rounding to the nearest 10 mg involves looking at the last digit of the number and rounding it up or down accordingly.
