Solve the following proportion Start Fraction x over 2 End Fraction equals Start Fraction 8 over 9 End Fraction (1 point) 144 0.

daser333 [38]

Answer:

1.78

Step-by-step explanation:

$\frac{x}{2} = \frac{8}{9}$

To solve for x we need to cross multiply it

We have = sign inbetween the fractions so we cross multiply it

9*x = 2* 8

9x = 16

Now we divide by 9 on both sides

$x= \frac{16}{9}$

so x= 1.7777777778

When we round to two decimal places then

x= 1.78
