Question

Divide 297 into three parts which are in the ratio 5 : 13 :15​

Answer 1

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

Answer 2

45:117:135

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!
