Two numbers are in the ratio 3:4 when 4 is added to each term their ratio becomes 10:13. Find the numbers.​
Alex17521 [72]
So there’s 2 steps to this. First we subtract what was added on both sides. 10-4 : 13-4 and we get 6:9. This ratio is true, but is not in simplest form, since both numbers are divisible by 3. So after dividing both sides by 3, the answer in simplest form will be 2:3. The correct answer is 2:3

sattari [20]
Simple...

you have: 3(a+4)=3a+4

Thus, your answer.
