STEP 1: Figure out what the numerator or
denominator is multiplied/divided by.
STEP 2: Do the same to the
numerator/denominator of the missing
number.
*Remember you have to multiply/divide
both the numerator and denominator by
the same number.
Divide both numerator and
denominator by the GCF or any common
factor until the only number you can divide
out of both is 1.

Example:
Click for
answer
STEP 1: Borrow 1 from the whole number.
STEP 2: Add that 1 to the fraction creating
a Mixed Number
STEP 3: Change this mixed number to an
improper fraction.
STEP 4: Add this improper fraction back
to the whole number creating a Hybrid.
STEP 5: Subtract numerators keeping the
denominator the same.
STEP 6: Subtract whole numbers
