Answer:
A 30/100 x 81
B 0.3 x 81
D. 3/10 x 81
Explanation:
Given the expression:
[tex]30\%\text{ of 81}[/tex]Recall that a percentage is a part of 100.
Therefore: 30% = 30/100
[tex]30\%\text{ of 81}=\frac{30}{100}\times81\text{ (Option A)}[/tex]Next, if we convert 30/100 to a decimal, we have that:
[tex]\frac{30}{100}\times81=0.3\times81(\text{Option B)}[/tex]From option A, if we cancel out a zero in the numerator and denominator, we have:
[tex]\frac{30}{100}\times81=\frac{3}{10}\times81(\text{Option D)}[/tex]The correct choices are A, B, and D.
