Any number can be made into a fraction by adding a denominator of what ?
ONE
If you multiply or divide the numerator and denominator by the same number what do you get ?
YOU GET AN EQUIVALENT FRACTION ππ
a fraction is fully reduced when the only number that divides evenly into both the ββ-
Numerator and denominator is 1.
We can multiply fractions with any β
Denominator!!
Step 1 of multiplying fractions is ββ
Multiply the numerators !
Step 2 of multiplying fractions is β
Multiply denominators !
Step 3 of multiplying fractionsββ
Simply if needed !!
We can only add and subtract fractions if they are written with the same β-
Denominator!!
Step 1 of β/β fractions
Rewrite as - - - - - - - - - - fractions with the same - - - - - - - - - - - .
1.) equivalent
2.) denominator
Step 2 of β/β fractions
Add or subtract the β
Numerator
Step 3,4 β/β fractions
The ββ- stays the same
And simplify if possible .
Denominator
We can divide fractions by rewriting as β-
KCF π
Step 1 : β
The first fraction ββ-
πππ
Stays the same !!
Step 2 : β
Division becomes what π₯β
Division becomes βοΈ
Step 3 : β
- - - - take the - - - - - - - - - - - of the second fraction π₯²
1.) Flip
2.) reciprocal
