how do u find unit rates and how would u round it to the nearest hundreth is it is necessary???
To find a unit rate, you need to determine the ratio between two quantities with different units. The unit rate represents the amount of one unit per one unit of another quantity. Here's a step-by-step explanation:
1. Identify the given quantities: Let's say you have a situation where you need to find the unit rate of miles per hour, and you're given the distance traveled in miles and the time in hours.
2. Calculate the ratio: Divide the given quantity by the other. For example, if you traveled 100 miles in 2 hours, the ratio would be 100 miles รท 2 hours = 50 miles per hour. This means you traveled at a rate of 50 miles every hour.
3. Rounding to the nearest hundredth: If necessary, you can round the unit rate to the nearest hundredth. In this case, the number of miles per hour might not require rounding unless specifically stated. However, for other cases where rounding is needed, follow these steps:
- Look at the digit immediately to the right of the hundredth place value.
- If that digit is 5 or greater, increase the hundredth place value by 1.
- If it's less than 5, keep the hundredth place value as it is.
- Remove all digits after the hundredth place value.
For example, if the unit rate is 7.2569, rounding it to the nearest hundredth would result in 7.26.
