Question

If x:y=11:8 and z:y=6:7

(i) Calculate x:y:z

(ii) x:z​

Answer 1

Answer:

77:56:48

77:48

Step-by-step explanation:

If x:y=11:8 and z:y=6:7

then;

x/y = 11/8 and z/y = 6/7

11y = 8x and 6y = 7z

x = 11y/8 anad z = 6y/7

Hence;

x:y:z

= 11y/8:y:6y/7

= 11/8:1:6/7

= 11/8 * 7/6

= 77:56:48

x:z = 11y/8:6y/7

x:z = 11/8:6/7

x:z = 77:48
