Which of the following statements is wrong?

Correct option is D

Solution:

A: Same numerator (2). Smaller denominator gives larger value.

​$$\frac{2}{5} > \frac{2}{7}$$ (correct)​

B: Same denominator (9). Larger numerator gives larger value.

​$$\frac{7}{9} > \frac{5}{9}$$(correct)​​

C: $$\frac{10}{11} = \frac{10 \times 10}{11 \times 10} = \frac{100}{110}$$(correct)​

D: $$\frac{3}{8} > \frac{7}{12}$$​​

Cross multiply:

3 × 12 = 36

7 × 8 = 56

Since (36 < 56),

$$\frac{3}{8} > \frac{7}{12}$$​ (wrong)

So, statement D is wrong.
