1.	Which of the following is not correct (not equal)?A) \(\frac{2}{3}\)= \(\frac{84}{75}\)B) \(\frac{3}{8}\) = \(\frac{375}{1000}\)C) \(\frac{70}{10}\)= \(\frac{7000}{1000}\)D)\(\frac{25}{45}\) = \(\frac{125}{175}\)
Answer» D)\(\frac{25}{45}\) = \(\frac{125}{175}\) (A) 84/75 = \(\frac{262\times3\times7}{3\times5^2} = \frac{2^2\times7}{5^2}\) = \(\frac{4\times7}{25}\) = \(\frac{28}{25}\neq\frac23\) (B) 375/1000 = \(\frac{3\times5^3}{3\times5^3}=\frac{3}{2^3}=\frac38\) (C) 7000/1000 = 7/1 = 70/10 (D) 125/225 = \(\frac{5^2}{3^2\times5^2}\) = \(\frac59=\frac{5}9\times\frac55=\frac{25}{45}\) = 125/225 Correct option is A) \(\frac{2}{3}\)= \(\frac{84}{75}\)

Which of the following is not correct (not equal)?A) \(\frac{2}{3}\)= \(\frac{84}{75}\)B) \(\frac{3}{8}\) = \(\frac{375}{1000}\)C) \(\frac{70}{10}\)= \(\frac{7000}{1000}\)D)\(\frac{25}{45}\) = \(\frac{125}{175}\)

Answer»

D)\(\frac{25}{45}\) = \(\frac{125}{175}\)

(A) 84/75 = \(\frac{262\times3\times7}{3\times5^2} = \frac{2^2\times7}{5^2}\) = \(\frac{4\times7}{25}\) = \(\frac{28}{25}\neq\frac23\)

(B) 375/1000 = \(\frac{3\times5^3}{3\times5^3}=\frac{3}{2^3}=\frac38\)

(D) 125/225 = \(\frac{5^2}{3^2\times5^2}\) = \(\frac59=\frac{5}9\times\frac55=\frac{25}{45}\) = 125/225

Correct option is A) \(\frac{2}{3}\)= \(\frac{84}{75}\)
