A triangle has sides of lengths 4.2, 5.7, and 7.2 inches. The smallest side of a similar triangle is 1.4 inches. What are the lengths of the other 2 sides? Write the smaller side length first and the larger side length second. The smaller side length is blank inches and the larger size length is blank inches.

We can set up a proportion to solve for the lengths of the other two sides. Let's call the lengths of the other two sides $x$ and $y$. We can write the proportion as:

$\frac{x}{y} = \frac{1.4}{4.2}$

To solve for $x$ and $y$, we can cross-multiply:

$4.2x = 1.4y$

Now, we can substitute the given values of $x$ and $y$ into the equation and solve for them.
