Respuesta :
let x be the common multiple.
therefore,
5x + 13x +15x=297
33x=297
x=297/33
x=9
5x=5*9=45
13x=13*9=117
15x=15*9=135
45+117+135=297
therefore,
5x + 13x +15x=297
33x=297
x=297/33
x=9
5x=5*9=45
13x=13*9=117
15x=15*9=135
45+117+135=297
Answer:
45:117:135
Step-by-step explanation:
We can solve this by turning each part into a fraction of the whole and multiply this by 297. To do this we first add the numbers in the ratio together to find out how many total divisions we have. 5+13+15 = 33
Let's start with 5. The amount in the 5 part of the ratio will be 5/33 so we can just multiply this fraction by 297 and it will give us the number.
5/33 x 297 = 45
We can then repeat this process with the other two parts:
13/33 x 297 = 117
15/33 x 297 = 135
Therefore our three parts are:
45:117:135
Hope this helped!
