Answer: 5.6

Step-by-step explanation:

5x:8=7:2

Ratio means division

So we can rewrite as

5x/8=7/2

Using cross multiply

5x×2=7×8

10x=7×8

10x=56

X=56/10

X=5.6

The value of X= 5.6

Answer:

x = 5.6

Step-by-step explanation:

Expressing the ratio in fractional form, that is

[tex]\frac{5x}{8}[/tex] = [tex]\frac{7}{2}[/tex] ( cross- multiply )

10x = 56 ( divide both sides by 10 )

x = 5.6
