Anna is preparing the soil in her garden for planting tomatoes. The directions say to use 4 pounds of fertilizer forb120 square feet of soil. The area of Anna's garden is 180 square feet. How much fertilizer is needed for a 180 square-foot garden?

6 pounds of fertilizers are needed for garden area of 180 square foot.

Step-by-step explanation:

Let 'x' pounds of fertilizers be needed for 180 square foot garden.

Given:

4 pounds of fertilizer needed for an area of 120 square foot.

The area of the garden given is 180 square foot.

Now, as per question:

4 pounds of fertilizer is equivalent to an area of 120 square foot.

Therefore, 'x' pounds of fertilizer is equivalent to an area of 180 square foot.

Applying proportion and cross multiplying method, we get:

Therefore, 6 pounds of fertilizers are needed for garden area of 180 square foot.

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.
