How do you reduce fractions using the GCF?
You divide the numerator (top) by the GCF to give you the numerator for the reduced fraction. You divide the denominator (bottom) by the GCF to give you the denominator of the reduced fraction. DONE! For example, 27/45 GCF(27, 45) = 9 Numerator of reduced fraction = 27/9 = 3 Denominator of reduced fraction = 45/9 = 5 So reduced fraction = 3/5
How do you put something into lowest terms?
To simplify a fraction, divide the numerator and the denominator by their GCF. Example: 30/42 The GCF of 30 and 42 is 6. 6 into 30 is 5 6 into 42 is 7 30/42 = 5/7 If the GCF of the numerator and the denominator is 1, the fraction is in its lowest terms.
Denominator and numerator of 18 fifths?
Denominator = 5, numerator = 18
How do you simplify 8 over 20?
8/20 = 2/5 (You divide the numerator and the denominator by the GCF, which in this situation is 4)
What is the numerator and denominator of five twelfths?
The numerator is 5 (five) and the denominator is 12 (twelve).
