Find an equivalent ratio so that the denominator = 1. This may require the numerator to be a fraction.
Step 1Practice doing addition, subtraction, multiplication, and division quickly in your head. About 1/3 of the math questions on the PCAT require you to simplify numerical expressions or solve simple word problems involving proportions. You won't have time to work out all of these problems slowly on paper. The more you can do in your head, the better you quantitative subscore will be.Now, second Step is: Review basic concepts of pre-calculus, focusing on functions. What is the limit behavior of a polynomial, exponential, or rational function? What do graphs of these functions look like? Review polynomial factoring as well.Step 3Review basic single variable calculus, focusing on derivatives and integrals. Polynomials, exponential functions, and rational functions will be tested on PCAT calculus.Step 4Don't worry about geometry, as this will not be tested. You may see a few questions that test your knowledge of sine, cosine, and tangent as functions.Step 5Learn to spot wrong answers at a glance. Each PCAT math question only has 4 choices, so if two (or three!) look wrong to you automatically, you'll be in good shape.
Provided that none of the denominators is 0 over their domains, the answer is quite simple. Multiply each term in the equation by the Least Common Multiple (LCM) of all the denominators and then simplify. Yo wil have an equation that is free of fractions. If that is not the case then things get much more complicated. You need to establish whether the numerator or denominator tends to zero faster. You are now in the territory of limiting values or orders of magnitude. The nature of your question suggests that you do not require an explanation of these concepts.
as whole numbers does not contain negative numbers, so for denoting ( eg: deapth of the sea,etc )negative things they require an extension.
