Equivalent, Simplifyingand Comparing Fractions By : YuHan
Equivalent Fractions 1Equivalent Fractions are 2 fractions that have thesame value but a different Numerator andDenominator. Our question is 4/5 = Y/35. Toknow the numerator of 35 (Y), you will need todivide the lower denominator (5) into the higherdenominator (35). Then, take you’re answer (7)and multiply that by the known numerator (4).Your answer is the unknown 28.
Simplifying Fractions 1T Simplify Multiplication Fraction Problem : oYou can simplify a multiplication problem whenthe ﬁrst fractions numerator is a multiple of thesecond fractions denominator. You can alsosimplify the second fractions numerator with theﬁrst fractions denominator.
Simplifying Fractions 2Simplifying a Division Fraction Problem :You can simplify a division fraction problem bydoing the exact same steps as simplifying aMultiplication Fraction problem. But you have toﬂip the second fractions numerator anddenominator around before you simplify.
Comparing Fractions 1Fractions with the same denominator is called aLike Fraction and fractions with differentdenominator is called a Unlike Fraction. T see owhich like fractions is greater, the fraction withthe greater numerator is bigger.
Comparing Fractions 2T calculate which fractions with the same onumerator is bigger, you will have to see whichdenominator is smaller. The smaller thedenominator, the less parts the fraction has,making the numerator bigger.
Comparing Fractions 3How do you see which fraction is bigger whenthey both have a different denominator and anumerator? One of the ways is to ﬁrst ﬁnd thelowest common denominator of both thedenominators. Now multiply the numerator byhow much you multiplied to get thedenominator. After you do those steps onboth the -
Comparing Fractions 4fractions, they are now like fractions. Thefraction with the bigger numerator is greater.
