A. 6 to 9 7'5 $\frac{6}{9}=\frac{2}{3} , \frac{9}{12}=\frac{3}{4}$

{$\frac{3X3}{3X4}=\frac{3}{4}$}

B. 9 to 12 7'5 $\frac{9}{12}=\frac{3}{4} , \frac{15}{20}=\frac{3X5}{4X5}=\frac{3}{4}$

C. $\frac{15}{20}=\frac{3}{4} ,$ 24 = 32 = 3 × 8: 4 ×8 = 3 = 4

D. $\frac{30}{40}=\frac{3X10}{4X10}=\frac{3}{4} , 18:24=3X6=4X6=3:4$
