Answer:
Hence, choice B is true.
Step-by-step explanation:
We are asked to find which value is similar to the value of the expression:
30% of 81.
We know that 30% of 81 could also be represented mathematically as:
30%×81=[tex]\dfrac{30}{100}\times 81[/tex]
which could also be written as:
[tex]0.3\cdot 81-----------(1)[/tex]
choice A:
[tex]\dfrac{30}{100}\cdot 81\cdot 100[/tex]
= [tex]30\cdot 81[/tex]
Which is not similar to equation (1).
Hence choice A is not similar.
Choice B:
[tex]0.3\cdot 81[/tex]
This expression is similar to equation (1).
Hence choice B is true.
Choice C:
[tex]0.03\cdot 81[/tex]
Which is not similar to equation (1).
Hence, choice C is not true.
Choice D:
[tex]\dfrac{3}{10}\cdot 81\cdot 10[/tex]
=[tex]3\cdot 81[/tex]
Which is not similar to equation (1).
Hence, choice D is not true.
Choice E:
[tex]30\cdot 81[/tex]
Which is not similar to equation (1).
Hence, choice D is not true.
