Flip the second fraction and Multiply! (KCF)

Multiply the top (numerators), multiply the bottom (denominators). Simplify.

Find a common denominator, then find the equivalent fractions, then add numerators, denominator stays same. Simplify.

Move the outside decimal to the wall, then move in the inside decimal same amount of spaces. Put inside decimal above ÷ line, Divide like normal.

Multiply like normal, count decimals places, move the decimal starting from the right to the left, the same amount of spaces

Line up your place values, put zeros in your blank spaces, then add or subtract depending on the problem

Ni/Do (numerator in, denominator out), then add a decimal and two zeros and divide.

Move the decimal TWO places to the RIGHT

Move the decimal TWO places to the LEFT

Put the number above its last place value, then Simplify.
