o How=to=convert=a=fraction=to=percent?=-
=CORRECT=ANSWER-

Divide=the=top=of=the=fraction=by=the=bottom,=multiply=by=100=
&=add=%=sign.
o Ex.=2/3===66.7%

o How=to=convert=a=percent=to=fraction?=-
=CORRECT=ANSWER-

Step=1:=Write=down=the=percent=divided=by=100=like=this:=perc
ent/100
o Step=2:=If=the=percent=is=not=a=whole=number,=then=multiply=b
oth=top=and=bottom=by=10=for=every=number=after=the=decimal=
point.=(For=example,=if=there=is=one=number=after=the=decimal,
=then=use=10,=if=there=are=two=then=use=100,=etc.)

o Step=3:=Simplify=(or=reduce)=the=fraction
o Ex.=75%===75/100===15/20===3/4

o Convert=62.5%=to=a=fraction=-=CORRECT=ANSWER-
Ex.=Step=1:=write=down.
o 62.5%===62.5/100=
o Step=2:=multiply=both=top=&=bottom=by=10.
o ==62.5/100=*10===625/1000
o Step=3:=Simplify=the=fraction.

, o 625/1000=Divided=by=25===25/40=can=go=lower=if=divided=by=5=
which===5/8

o A=sample=contains=2/3=oz.=of=liquid.=How=many=milliliters=(m
L)=is=this?=-=CORRECT=ANSWER-
To=convert=oz.=to=mL,=multiply=by=30=oz./mL.
o 2/3=*=30===60/3===20

o Instructions=require=you=to=dilute=a=powder=in=3=quarts=of=wate
r.=You=only=have=a=container=that=is=marked=in=liters.=How=ma
ny=liters=would=you=use=to=dilute=the=powder?=-
=CORRECT=ANSWER-1=Quart===32=oz=

o Therefore,=3=Quarts===96oz.
o There=are=30=milliliters=per=oz.,=so=96=oz.===2,880=milliliters
o There=are=1000=milliliters=per=liter,=so=2,880=mL===2.88=Liters

o Or=

o 1=Quart===0.946=Liter=*3==2.838===2.88=L

o 35%=to=fraction=-=CORRECT=ANSWER-35/100===7/20

o 0.7/10===N/100=-=CORRECT=ANSWER-
cross=multiply===10N/70=7
o or==0.7*100/10===0.7*10===7

o 1=inch===-=CORRECT=ANSWER-2.54=centimeters

o 1=foot===-=CORRECT=ANSWER-
30.48=centimeters=or=0.3048=meters
