Question
Easy
Let a, b, c be three rational numbers, where a = $\frac{3}{5}$, b=$\frac{2}{3}$ and c=$\frac{-5}{6}$. Which one of the following is true?
1
$a\times(b+c) = b\times(a+c)$
2
$a+(b+c) = b+(a+c)$
3
$a+(b+c) = c+(a+b)$
4
$a-(b-c) = c-(a-b)$

Correct Answer
Option C
Explanation
To determine why Option 3 is the correct answer, let's evaluate each option using the given rational numbers: \( a = \frac{3}{5} \), \( b = \frac{2}{3} \), and \( c = \frac{-5}{6} \). ### Option 3: \( a + (b + c) = c + (a + b) \) Let's calculate both sides of the equation: 1. Left Side: \( a + (b + c) = \frac{3}{5} + \left(\frac{2}{3}…Read More
