x = 12.75

Step-by-step explanation:

10.2 : x = 0.8

x = 10.2 : 0.8

= 102/10 : 8/10

= 102/10 × 10/8

Answer:

12.75

Step-by-step explanation:

if 10.2 /y= 0.8,

then 10.2/y = 0.8/1.

( cross multiply ), we have that

10.2*1=9.8*y

so,10.2=0.8y

(divide both sides by the coefficient of y)

y=10.2/0.8

y = 12.75
