Answer 2

Answer:

The full expression will be 90:390::890:3856.67

Step-by-step explanation:

• Proportion: Proportion is the comparison of two ratios. The ratio of first and second proportions is equal to the ratio of third and fourth proportions.
• Example- a:b::c:d. We can express this relation like, $\frac{a}{b} = \frac{c}{d}$.

        Fourth proportion = d = $\frac{b\times c}{a}$

• Solution: The given problem is, 90:390::890=-------------

       Here we have to find the fourth proportion.

       Suppose the fourth proportion is 'x'.

        The expression will be -  90:390::890:x

                                                   $\frac{90}{390} = \frac{890}{x}$

                                                   x =  $\frac{890\times 390}{90}$ = 3856.67

      ∴  The full expression will be 90:390::890:3856.67
