Answer:
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
= 102/8
= 12.75
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
