Fraction => Decimal
Numerator ÷ denominator = decimal
¾ = 3÷4= 0.75
Fraction => Percent
Numerator ÷ denominator x 100 = percent
¾ = 3 ÷ 4 x 100 = 75%
Decimal =>Percent
Decimal x 100 = percent
0.75 x 100 = 75%
Decimal => Fraction
Numerator = decimal
Denominator= place value of last non-zero number in the decimal
*Make sure to simplify to lowest terms*
0.75 : numerator is 75 and the denominator is 100 because 5 is in the
hundredths place so 0.75 = 75/100 = ¾
Percent => Decimal
Percent ÷ 100 = decimal
75% ÷ 100 = 0.75
Percent => Fraction
Numerator = percent
Denominator= 100
*Make sure to simplify to lowest terms*
75% = 75/100 = ¾
