4/9 times 81 I just cant figure it out
4/9 × 81/1 ( the fraction still equals 81)
Now cross cancel;
4/1 × 9/1
multiply numerators;
4 × 9 = 36
multiply denominators;
1 ×1 = 1
so 4/9 × 81 = 36/1 or in simplest form = 36
\(\frac{4}{9} \times 81 = \frac{4}{9} \times 9\times 9 = \frac{4\times9\times9}{9} = \frac{4\times9}{1} = 4\times 9 =\boxed{\bf{36}}\)
