To find two different numbers that, when rounded to the nearest tenth, will give you 18.3, we can use the formula for rounding.
The rounding formula for a given number n to the nearest tenth is:
rounded_number = round(n * 10) / 10
Let's use this formula to find the numbers:
1. Start by assuming a number greater than 18.3, let's say 18.35.
2. Multiply this number by 10: 18.35 * 10 = 183.5.
3. Round this result to the nearest whole number: round(183.5) = 184.
4. Divide the rounded result by 10: 184 / 10 = 18.4.
5. So, 18.35 rounded to the nearest tenth is 18.4. This does not give us 18.3, so it is not one of the desired numbers.
Now, let's try a number smaller than 18.3, for example, 18.25:
1. Multiply this number by 10: 18.25 * 10 = 182.5.
2. Round this result to the nearest whole number: round(182.5) = 183.
3. Divide the rounded result by 10: 183 / 10 = 18.3.
4. So, 18.25 rounded to the nearest tenth is 18.3. This is one of the desired numbers.
Now, let's find another number different from 18.25 but also rounded to 18.3:
1. Assume a number smaller than 18.25, for example, 18.245.
2. Multiply this number by 10: 18.245 * 10 = 182.45.
3. Round this result to the nearest whole number: round(182.45) = 182.
4. Divide the rounded result by 10: 182 / 10 = 18.2.
5. So, 18.245 rounded to the nearest tenth is 18.2. This is another desired number.
Therefore, two different numbers that, when rounded to the nearest tenth, give you 18.3 are 18.25 and 18.245.
