For now we do not know what u equals, but we do know that 20/5 = 4, because 20/5 simplified is just 4 since the fraction means 20 ÷ 4. Now that we are back to the question, with 2/5; if you multiply by 10 the numerator will then be 20. And now the equation is true! Hope this helps!
The transitive property states that: If q = r and r = s, then q = s. In other words, if q is related to r by some property, and r is related to s by the same property, then q is related to s by that property.
