5.4% rounded up to 1 decimal point
The numbers are 24 and 72
Step-by-step explanation:
- Step 1: Let the small number be x. Then the larger number = 3x. Difference = 48
⇒ 3x - x = 48
⇒ 2x = 48
⇒ x = 24
⇒ 3x = 3 × 24 = 72
N/3 - 5 = 13
(N-15/3) =13 taking lcm
N-15 = 13×3
N-15 = 39
Therefore, N = 39+15 = 54

2500 X 15 = 37500
37500 ÷ 100 = 375
375 + 200 = 575
The answer is C.

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 answer is D.
