What iis ia iproper ifraction? i- iCorrect iAnswer-A ifraction iwhere ithe inumerator iis
ismaller ithan ithe idenominator.
What iis ian iimproper ifraction? i- iCorrect iAnswer-A ifraction iwhere ithe inumerator
iis ilarger ithan ithe idenominator.
What ican ian iimproper ifraction ibe ichanged ito? i- iCorrect iAnswer-A imixed
inumber.
What iis ia imixed inumber? i- iCorrect iAnswer-A imixed inumber iis ia iwhole inumber
iand ia iproper ifraction.
How ido iyou ichange ian iimproper ifraction ito ia imixed inumber? i- iCorrect iAnswer-
Divide ithe idenominator iinto ithe inumerator. iThe iresult iis ithe iwhole inumber. iThe
iremainder iis ithe inumerator iof ithe iproper ifraction, iand ithe ivalue iof ithe
idenominator idoes inot ichange. i
Example: i5/2 iis i2 i1/2 ibecause i2 igoes iinto i5 itwice iwith ia iremainder iof i1.
,How ido iyou ichange ia imixed inumber ito ian iimproper ifraction? i- iCorrect iAnswer-
Multiply ithe iwhole inumber iby ithe idenominator iand iadd ithe iresult ito ithe
inumerator. iThe iresults ibecome ithe inew inumerator. i
Example: i2 i1/2 iis i5/2 ibecause i2 itimes i2 iplus i1 iis i5 ifor ithe inew inumerator.
What iis ithe ileast icommon idenominator? i- iCorrect iAnswer-The ismallest inumber
ithat ican ibe idivided ievenly iinto ithe idenominators iof iall ifractions ibeing icompared.
How ido iyou ichange ia idecimal ito ia ifraction? i- iCorrect iAnswer-1. iWrite ithe
idecimal idivided iby i1 iwith ithe idecimal ias ithe inumerator iand i1 ias ithe
idenominator. i
2. iMultiply ithe inumerator iand idenominator iby i10 ifor ievery inumber iafter ithe
idecimal ipoint. i
Example: iif ithere iis i1 idecimal iplace, imultiply iby i10. iIf ithere iare i2 idecimal
iplaces, imultiply iby i100. i
3. iReduce ithe ifraction icompletely. i
Example: i0.37
1. i0.37/1
2. i0.37 ix i100/1 ix i100 i= i37/100
3. i37/100 i(this ifraction idoes inot ireduce)
Steps ito ichanging ia ifraction ito ia idecimal. i- iCorrect iAnswer-1. idivide ithe
inumerator iby ithe idenominator. iAdd izeros iafter ithe idecimal ipoint ias ineeded. i
, 2. icomplete ithe iprocess iwhen ithere iis ino iremainder ior ithe idecimal iis irepeating.
2 iways ito iconvert ia idecimal ito ia ipercent. i- iCorrect iAnswer-1. imultiply ithe
idecimal iby i100 iand iadd ia ipercent isign.
2. imove ithe idecimal ipoint i2 iplaces ito ithe iright.
2 iways ito iconvert ia ipercent ito ia idecimal. i- iCorrect iAnswer-1. iremove ithe ipercent
isign iand idivide ithe idecimal iby i100. i
2. imove ithe idecimal ipoint i2 iplaces ito ithe ileft.
Steps ito ichange ia ifraction ito ia ipercent. i- iCorrect iAnswer-1. idivide ithe inumerator
iand idenominator.
2. imultiply iby i100 iand iadd ia ipercent isign.
Steps ito ichange ia ipercent ito ia ifraction. i- iCorrect iAnswer-1. iRemove ithe ipercent
isign iand iwrite ithe ivalue ias ithe inumerator iwith ia idenominator iof i100. i
2. iSimplify ithe ifraction.
Term ifor ifractions iwith ithe isame idenominator. i- iCorrect iAnswer-Like ifractions.
How ido iyou iadd ilike ifractions? i- iCorrect iAnswer-Add ithe inumerators. i
Example: i2/5 i+ i1/5 i= i3/5
How ido iyou isubtract ilike ifractions? i- iCorrect iAnswer-Subtract ithe inumerators. i
Example: i8/9 i- i2/9 i= i6/9 i= i2/3
