Which simplified fraction is equal to 0.53 repeat ? A.24/46 B.8/15 C.42/90 D.5/9
murzikaleks [220]

Answer:

To see how these fractions are equal, I divided the numerators by the denominators. For instance, you could have 4 over 5 (4/5) and divide 4 by 5 (4/5) to get 0.8. Now you'll do the same thing for the fractions given

24/45=0.533...

8/15=0.533...

48/90=0.533...

5/9=0.5556

As you can see, the only fraction that doesn't equal 0.53, or the outlier, is 5/9 or 0.5556

vova2212 [387]

Answer:

4.25%

Step-by-step explanation:

<u>Step 1: Calculate the commission paid</u>

<em>Commission = Gross earning - base salary</em>

<em>Commission = 441.3 - 375</em>

Commission = 66.3

<u>Step 2: Calculate the commission sales</u>

<em>Commission sales = Total sales - quota sales</em>

<em>Commission sales = 6560 - 5000</em>

Commission sales = 1560

<u>Step 3: Calculate the rate of commission</u>

<em>x% of 1560 = 66.3</em>

<em>x% * 1560 = 66.3</em>

<em>x% = 0.0425</em>

x = 4.25%

Therefore, the rate of commission was 4.25%.
