A number, when subtracted from 3 times the second number, gives a result equal to $\frac{3}{4}$ of the first number. What is the ratio of the first number to the second number? |
11 : 6 12 : 7 9 : 5 10 : 7 |
12 : 7 |
First number = A Second number = B ⇒ 3B - A = \(\frac{3}{4}\)A ⇒ 3B = \(\frac{3}{4}\)A + A ⇒ 3B = \(\frac{7}{4}\)A ⇒ 12B = 7A ⇒ A : B = 12 : 7. |
