Which of the following options have the same value as 10% of 33?
DIA [1.3K]

Answer:

<em>C. 1/10 • 33</em>

<em>D. 0.1 • 33</em>

<em>E. 10/100 • 33</em>

Step-by-step explanation:

Knowing that

10% = 0.1 in decimal form

10% = 1/10 or 10/100 in fraction form

of = multiply

<em>Thus, the following is correct:</em>

<em>C. 1/10 • 33</em>

<em>D. 0.1 • 33</em>

<em>E. 10/100 • 33</em>

<u><em>We can also solve to find the answer:</em></u>

<em>10% of 33 = 3.3</em>

<em>0.1 x 0.33 = 0.033</em>

<em>10 x 33 = 330</em>

<em>1/10 x 33 = 3.3</em>

<em>0.1 x 33 = 3.3</em>

<em>10/100 x 33 = 3.3</em>

<u><em>Hence answer =</em></u>

<em>C. 1/10 • 33</em>

<em>D. 0.1 • 33</em>

<em>E. 10/100 • 33</em>
