Karen works for 85 hours over a two week period. SHe earns $1,891.25 over this period. How much does Karen earn for 8 hours of w
Gekata [30.6K]
If karen works 85 hours within two weeks and earns $1,891.25, you'd set up an equation like this, to find the value of x ----

x=amount of money per hour Karen works 

85x=<span>1,891.25

then divide </span><span>1,891.25 by 85 

x=</span>22.25

this says that karen gets $22.25 for every hour she works.... then to find how much she works for 8 hours you want to multiply the amount of money she gets per hour by 8 hours. 

22.25 x 8 = 178

Karen earns $178 after working 8 hours.

Ratioz rate unit rate <br>I have a quiz tmr 7th grade I need to learn ratio, rate unit rates!!! ​
posledela

Alright! I'll help you. Let me tell you what's ratio, rate unit rates all about! :D

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

What is the difference between a unit rate and a ratio?

Guide the discussion so that students understand that a ratio is simply the quotient of two numbers, while a rate is the ratio of two measurements that have different units (like miles and hours, or dollars and ounces). Reinforce the fact that a rate is usually expressed in per unit form, where the denominator is 1.

What are some examples of ratios?

In mathematics, a ratio is a relationship between two numbers indicating how many times the first number contains the second. For example, if a bowl of fruit contains eight oranges and six lemons, then the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).

Is a rate always a ratio?

Rates and ratios. ... A rate is a little bit different than the ratio, it is a special ratio. It is a comparison of measurements that have different units, like cents and grams. A unit rate is a rate with a denominator of 1.

How do I find the unit rate?

To get the unit to equal 1, divide both numbers by the denominator; your answer is the number you get by dividing the numerator by the denominator. Use this method to calculate unit cost, too—you're calculating how much 1 item is worth, after you're given the amount that multiple items cost.

Here are some questions and how to answer them to help you! I hope this helps you! c:
