Question

please answer by solving
if x is 80% of Y and y 90% of Z then find the ratio of x:z​

Answer 1

Answer:

18 : 25

Step-by-step explanation:

Let z is 100. Then,

y is 90% of z => y = 90/100 × 100

y = 90

x is 80% of y => x = 80/100 × 90

= 72

Therefore, x:z => 72 : 100 = 18 : 25

Plz mark me as the brainliast.

Answer 2

Answer:

X : Y : Z = 36 : 45 : 50

X : Z = 36 : 50.

Step-by-step explanation:

X = 80/100 Y Y = 90/100 Z

X= 4/5 Y. Y = 9/10Z

X/Y = 4/5. Y/Z = 9/10

X : Y = 4 : 5. Y : Z = 9 : 1

X : Y = 4 : 5

Y : Z = 9 : 10

X : Y : Z = 36 : 45 : 50
