Answer:
To cancel down the fraction 21/33, you need to find the greatest common factor (GCF) of the numerator (21) and the denominator (33) and then divide both the numerator and denominator by this common factor.
The GCF of 21 and 33 is 3.
So, divide both the numerator and denominator by 3:
(21 ÷ 3) / (33 ÷ 3) = 7/11
The fraction 21/33 can be canceled down to 7/11 in its simplest form.
