it works when comparing fractions by multiplying the fractions to see whitch one is greater not greater and equal

Yes, because for any x and y that are positive fractions (y not equal to zero), x/y is also a positive fraction. Note that whole numbers are considered fractions with denominators of 1 -- otherwise it doesn't work.

When you are multiplying with mixed number fractions, it becomes easier to work with improper fractions instead. For example, 2 1/3 x 1 1/2 (two and a third times one and a half) is 2 x 1 + 2 x 1/2 + 1/3 x 1 + 1/3 x 1/2 But with improper fractions, it's 7/3 x 3/2 = 7/2 = 3 1/2

Using the scientific method, scientists can work together to test different hypotheses and determine the best solution for the problem

pros; you will learn to be smarter. cons; you will waste ALL your time, get angry, and punch your teacher for making you do the work.

What the butterfly method does is to make the fractions equivalent fractions with a new denominator (bottom number) the product of the original denominators (bottom numbers). Then to compare/add/subtract the fractions, the numerators (top numerators) can be compared/added/subtracted.Let the two fractions be a/b and c/d, then the new denominator is bd (b times d). Then the equivalent fractions are:a/b ⇒ (a x d)/(b x d) ⇒ ad/bdc/d ⇒ (b x c)/(b x d) ⇒ bc/bd

This is related to the fact that dividing by a number is the same as multiplying with the number's reciprocal.

Title: Introduction to Fractions Objective: Students will be able to identify, represent, and compare fractions. Introduction (5 mins) - Review what fractions are and why they are used. Identifying Fractions (10 mins) - Show various fractions and have students identify the numerator and denominator. Representing Fractions (15 mins) - Students use visual aids (like fraction bars) to represent given fractions. Comparing Fractions (10 mins) - Students compare fractions using visual aids and identify which fraction is greater or less than the other. Practice (10 mins) - Students work on exercises in their workbook to apply what they have learned. Conclusion (5 mins) - Review key concepts learned today and summarize the lesson.

Mixed Fractions are fractions that have whole numbers and fractions on the side.If you are trying to change them into improper fractions you take the denominator of the fraction and multiply it by the whole number and keep the same numerator. ex.: 2 and one fourth =

Many of them.

Use the GCF to reduce fractions. Use the LCM to add and subtract unlike fractions. Carpenters work with fractions a lot.

You cannot add or subtract fractions with different denominators. If the denominators are different then you need to work with equivalent fractions.
