The area of a blackboard is

square yards. a poster's area is

find the unit rate and explain in words what the unit rate means in the context of this problem. is there more unit than one unit rate that can be calculated? how do you know

i need pls give me the right answer

Step-by-step explanation:

The unit rate refers to how many area units of the poster are in the blackboard.

To find this rate, we just have to divide the area of the blackboard by the area of the poster.

Where represents the area of the blackboard in square yards.

Where represents the area of the poster.

Now, the ratio is

This mean that the unit rate is 1.5, that is, there are 6 square yards of blackboard per 2 square yards per poster.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
