<span>It is important to know rational expression because we come across rational expressions most of the time in the real world, often without even realizing it. </span><span> </span><span>Example: you may want to know how much of a 25% chemical solution need to be added to 1L of water to produce a 10% solution. </span><span> </span><span>Ans: Equation:
</span> <span /><span>solution + water = solution
</span><span>0.25x + 0*1 L = 0.10(x+1)
</span> <span /><span>Multiply the above equation by 100 to get:
25x + 0 = 10x + 10
15x = 10
x = 2/3 Liter (amt. of 25% solution in the mixture)</span>
What were the major causes of the American Revolution? The American Revolution was principally caused by colonial opposition to British attempts to impose greater control over the colonies and to make them repay the crown for its defense of them during the French and Indian War (1754–63)
