Tips for Fraction Word Problems - Word problems that involve fractions are often considered difficult for students resulting in reluctance in attempting the questions. Yes, they are a bit more complex than the normal word problems. However, using the right tips and rules, these questions can be solved by any student. All you need to do is practice. Let's try understanding certain examples. Multiplying Fraction word problems: While at a bakery, a woman purchased bought half a pound of chocolate fudge cake. She ate that cake at night after dinner around ¼ of it. How much is left? Dividing Fraction Word Problem: Jamal's mother made his favorites, peanut butter caramel fudge cake around 1/3 of pound. She divided the fudge into four equal pieces. How much cake will go into each container? Tips: 1.You need to read the problem carefully at first. 2.Give it another read, if you are still not able to understand. 3.Explain that problem in your own words to someone else (a friend or a teacher). 4.Focus on every single sentence. 5.Use visual representation to better understand the problem. 6.Discuss the answer with someone to be sure it is making any sense. 7.Practice the same problem with different variables and numbers. Students learn how to handle word problems that include and use fractional values.

Quick Operation Review with Fractions
When you are working with word problems that involve fractions it is good to refer back to the basic foundation of the math that is required. The universal rule when working with these types of problems is to ensure that you are working with fraction values that share a common denominator. The beauty of this is that you do not have to worry about using the least common denominator at first as long as you reduce the final fraction. Find a common denominator between the values that you find easy to work with. When you have both values in that format, addition and subtraction are simple. Just add the numerators for addition and subtract the numerators for subtraction. The denominator will not change. The operation just takes place at the numerator level. When it comes to multiplication, we do not need to worry about finding a common base, just multiply the numerators and denominators of the fractions together. Division is much the same divide the numerators and the denominators. Those are the basic rules you will need to follow when processing these problems. The biggest challenge when working with these types of problems is determining which operation you will need to work with based on the situation. If you look for common keywords, you can quickly establish the type of math that is involved. For addition look for the words: combine(d), increase, join, together, and total. For subtraction look for the words or phrases: decrease, difference, left over, less than, reduce, remove, and take away. For multiplication look for the words or phrases: by, per, product of, and times. For division look for the words: average, equal parts, out of, ratio, shared, and split.
