a relationship between decimal, fraction, or 3 Three students wrote percentage. Maggie wrote 75% = Bieber wrote 0.05 = 50% Lee Yung wrote == 0.375 Whích students wrote a correct equation? A. All the above B. None of the above C. Beiber and Lee Yung only D. Lee Yung only 8

Respuesta :

To change decimal or fraction to percent multiply them by 100

Example: 1/4 x 100% = 25%, 0.2 x 100% = 20%

Let us check the answer of the 3 students

Maggie wrote 75% = 3/5

Since

[tex]\frac{3}{5}\times100=\frac{300}{5}=60[/tex]

Then 3/5 = 60%, not 75%

Maggie is wrong

Bieber wrote 0.05 = 50%

Let us check

0.05 x 100% = 5%, not 50%

Bieber is wrong

Yung wrote 3/8 = 0.375

Let us check

[tex]\begin{gathered} \frac{3}{8}\times100=\frac{300}{8}=\frac{\frac{300}{2}}{\frac{8}{2}}=\frac{150}{4} \\ \frac{150}{4}=\frac{\frac{150}{2}}{\frac{4}{2}}=\frac{75}{2}=37.5 \end{gathered}[/tex]

Since 0.375 x 100% = 37.5%

Yung is right

The answer is Lee Yung only

The answer is D
