Answer:
Option B is correct = [tex]0.3 \times 81[/tex]
Step-by-step explanation:
The complete question is: Which of the following options have the same value as 30% of 81?
Group of choices is:
(A) [tex]\frac{30}{100}\times 81 \times 100[/tex]
(B) [tex]0.3 \times 81[/tex]
(C) [tex]0.03 \times 81[/tex]
(D) [tex]\frac{3}{10}\times 81 \times 10[/tex]
(E) [tex]30 \times 81[/tex]
Now, the expression given to us is 30% of 81.
Simplifying the above expression we get;
30% of 81 = [tex]\frac{30}{100} \times 81[/tex]
= [tex]\frac{3}{10} \times 81[/tex] = [tex]0.3 \times 81[/tex]
Now, we will solve each of the given options and then see which option matches with our calculation.
Option (A) is given;
[tex]\frac{30}{100}\times 81 \times 100[/tex] = [tex]30 \times 81[/tex]
This doesn't match with our answer, so this option is not correct.
Option (B) is given;
[tex]0.3 \times 81[/tex]
This matches with our answer, so this option is correct.
Option (C) is given;
[tex]0.03 \times 81[/tex]
This doesn't match with our answer, so this option is not correct.
Option (D) is given;
[tex]\frac{3}{10}\times 81 \times 10[/tex] = [tex]3 \times 81[/tex]
This doesn't match with our answer, so this option is not correct.
Option (E) is given;
[tex]30 \times 81[/tex]
This doesn't match with our answer, so this option is not correct.
