I think 8.0km is the answer
First one is D and second one is C
The dollar amount of merchandise inventory is A. $28,800
Let N = be the missing number
1.) N/$45,000 = 2.65/1 (cross multiply to get the current assets)
N = $119,250
2.) N/$45,000 = 2.01 (cross multiply to get current the quick assets)
N = $90,450
3.) Since there are no prepaid expenses, subtract current quick assets from the current assets to get the merchandise inventory
$119,250 - $90,450 = $28,800
This one is deceiving my simple. Start with the ratio 2/3. To find more ratios that are proportionate, simply multiply the numerator and denominator by the same number. Let's go with 2. So, 2*2/2*3 (which is 4/6) should be equal to 2/3. If you plug both into a calculator, you will see that they both equal 0.667, and are therefore proportionate.
Here are some more examples:
2/3, 4/6, 6/9, 8/12, 10/15
