2500 X 15 = 37500 37500 ÷ 100 = 375 375 + 200 = 575 The answer is C.
16. The easiest way to answer this question is by going through each answer one by one:
14:6 = 28:18 28 <span>÷ 14 = 2 </span>18 <span>÷ 6 = 3 </span>Since both numbers were multiplied by different numbers, we can establish that this is not a true proportion.
42:7 = 6:2 42 ÷ 7 = 6 7 ÷ 7 = 1 42:7 = 6:1 By dividing both numbers by the same number, we can establish that the answer is wrong.
2:3 = 3:2 This is obviously wrong. That is because, in ratios, the order counts. So the first 3 is more than the first 2, therefore the second number on the other side of the ratio should be more than the first.
3:5 = 12:20 12 <span>÷ 3 = 4 </span>20 <span>÷ 5 = 4 </span>Since both numbers were multiplied by the same number, this is a true proportion.
The choices for this question is found elsewhere and as follows:
<span>A. 16/9
B. 4/3
C. 32/9
D. 64/27 </span> From the choices, i think the correct answer from the choices listed above is option B since from the situation you are reducing the ratio. Hope this answers the question.
