Let's solve each of these equivalent fractions problems step by step. The goal is to solve for $ X $ in each equation, where two fractions are set equal to each other.

We use the cross-multiplication method:
> If $ \frac{a}{b} = \frac{c}{d} $, then $ a \cdot d = b \cdot c $

1) $ \frac{1}{4} = \frac{X}{6} $

Cross-multiply:
$ 1 \cdot 6 = 4 \cdot X $ → $ 6 = 4X $
Divide both sides by 4:
$ X = \frac{6}{4} = \frac{3}{2} = 1.5 $

✔ Answer: $ \boxed{\frac{3}{2}} $

---

2) $ \frac{7}{13} = \frac{X}{26} $

Cross-multiply:
$ 7 \cdot 26 = 13 \cdot X $ → $ 182 = 13X $
$ X = \frac{182}{13} = 14 $

✔ Answer: $ \boxed{14} $

---

3) $ \frac{8}{26} = \frac{X}{13} $

Simplify $ \frac{8}{26} = \frac{4}{13} $, so:
$ \frac{4}{13} = \frac{X}{13} $ → $ X = 4 $

Or cross-multiply:
$ 8 \cdot 13 = 26 \cdot X $ → $ 104 = 26X $ → $ X = 4 $

✔ Answer: $ \boxed{4} $

---

4) $ \frac{X}{12} = \frac{6}{8} $

Simplify $ \frac{6}{8} = \frac{3}{4} $
So: $ \frac{X}{12} = \frac{3}{4} $
Cross-multiply: $ 4X = 36 $ → $ X = 9 $

✔ Answer: $ \boxed{9} $

---

5) $ \frac{1}{6} = \frac{2}{X} $

Cross-multiply: $ 1 \cdot X = 6 \cdot 2 $ → $ X = 12 $

✔ Answer: $ \boxed{12} $

---

6) $ \frac{X}{9} = \frac{2}{3} $

Cross-multiply: $ 3X = 18 $ → $ X = 6 $

✔ Answer: $ \boxed{6} $

---

7) $ \frac{2}{X} = \frac{4}{11} $

Cross-multiply: $ 2 \cdot 11 = 4 \cdot X $ → $ 22 = 4X $ → $ X = \frac{22}{4} = \frac{11}{2} = 5.5 $

✔ Answer: $ \boxed{\frac{11}{2}} $

---

8) $ \frac{X}{7} = \frac{8}{14} $

Simplify $ \frac{8}{14} = \frac{4}{7} $ → $ \frac{X}{7} = \frac{4}{7} $ → $ X = 4 $

✔ Answer: $ \boxed{4} $

---

9) $ \frac{X}{14} = \frac{6}{7} $

Cross-multiply: $ 7X = 84 $ → $ X = 12 $

✔ Answer: $ \boxed{12} $

---

10) $ \frac{X}{12} = \frac{4}{6} $

Simplify $ \frac{4}{6} = \frac{2}{3} $ → $ \frac{X}{12} = \frac{2}{3} $
Cross-multiply: $ 3X = 24 $ → $ X = 8 $

✔ Answer: $ \boxed{8} $

---

11) $ \frac{3}{14} = \frac{X}{7} $

Cross-multiply: $ 3 \cdot 7 = 14 \cdot X $ → $ 21 = 14X $ → $ X = \frac{21}{14} = \frac{3}{2} = 1.5 $

✔ Answer: $ \boxed{\frac{3}{2}} $

---

12) $ \frac{9}{X} = \frac{1}{4} $

Cross-multiply: $ 9 \cdot 4 = 1 \cdot X $ → $ X = 36 $

✔ Answer: $ \boxed{36} $

---

13) $ \frac{5}{X} = \frac{9}{14} $

Cross-multiply: $ 5 \cdot 14 = 9 \cdot X $ → $ 70 = 9X $ → $ X = \frac{70}{9} \approx 7.78 $

✔ Answer: $ \boxed{\frac{70}{9}} $

---

14) $ \frac{4}{5} = \frac{3}{X} $

Cross-multiply: $ 4X = 15 $ → $ X = \frac{15}{4} = 3.75 $

✔ Answer: $ \boxed{\frac{15}{4}} $

---

15) $ \frac{6}{7} = \frac{X}{21} $

Cross-multiply: $ 6 \cdot 21 = 7 \cdot X $ → $ 126 = 7X $ → $ X = 18 $

✔ Answer: $ \boxed{18} $

---

16) $ \frac{7}{9} = \frac{X}{27} $

Cross-multiply: $ 7 \cdot 27 = 9 \cdot X $ → $ 189 = 9X $ → $ X = 21 $

✔ Answer: $ \boxed{21} $

---

17) $ \frac{5}{X} = \frac{2}{9} $

Cross-multiply: $ 5 \cdot 9 = 2 \cdot X $ → $ 45 = 2X $ → $ X = \frac{45}{2} = 22.5 $

✔ Answer: $ \boxed{\frac{45}{2}} $

---

18) $ \frac{1}{6} = \frac{X}{24} $

Cross-multiply: $ 1 \cdot 24 = 6 \cdot X $ → $ 24 = 6X $ → $ X = 4 $

✔ Answer: $ \boxed{4} $
