------------------------------------------------ Which of the following options have the same value as [tex]40\%[/tex] of 84?

Choose 2 answers:

A) [tex]40 \cdot 84[/tex]

B) [tex]0.4 \div 84[/tex]

C) [tex]\frac{40}{100} \cdot 84[/tex]

D) [tex]84 \div 40[/tex]

E) [tex]0.4 \cdot 84[/tex]

Answer :

Answer:

The answers are C and E

Step-by-step explanation:

We want to do the 40% of 84, to do it you have to multiply 84 by 40 and then divide it by 100.

[tex]84*40 = 3,360\\\frac{3360}{100} = 33.60[/tex]

Answer C and E are the same operation:

[tex]\frac{40}{100} *84 = 0.4* 84 = 33.60\\[/tex]

You can notice that they are equal compared to the question asked.

If we look at the other answers, you will see that they are not equal.

Answer:

Option C and option E.

Step-by-step explanation:

Step 1:

Obtaining the value of 40% of 84. This is illustrated below:

40% of 84 = 40/100 x 84 = 0.4 x 84 = 33.6

Step 2:

Determination of the options that have same value as 40% of 84 i.e 33.6.

This is illustrated below:

For option A:

40⋅84 = 40 x 84 = 3360

For option B:

0.4 ÷ 84 = 0.0048

For option C:

40/100 ⋅ 84 = 40/100 x 84 = 0.4 x 84 = 33.6

For option D:

84 ÷ 40 = 2.1

For option E:

0.4 ⋅ 84 = 0.4 x 84 = 33.6

From the calculations made above, we can clearly see that option C and option E has the same value as 40% of 84.
