Question

If x: y = 7: 9 and y: Z = 5:4, then find the value of x:y:z.​

Answer 1

Answer:

The answer is 35:45:36

Step-by-step explanation:

• First, we need to take LCM ( lowest common multiple) of 9 and 5 because they are the values of y and they are appearing in both ratios as the value of the same variable, y.
• The LCM of 9 and 5 is 45. Now we need to multiple both ratios ( 7:9 and 5:4) so that we get 45.in both ratios as y's value.
• We multiply 7:9 with 5 and it becomes 35:45.
• We multiply 5:4 with 9 and we get 45:36.
• Now we can combine both ratios by taking values of x,y and z.

$35:45:36$
