Final Answer : E, Explanation :   To solve a proportion, we cross-multiply, which means we multiply the numerator of one fraction by the denominator of the other fraction. So: x ⋅ 20 = 5 ⋅ 7 x\cdot 20=5\cdot 7 x ⋅ 20 = 5 ⋅ 7 Simplifying: 20 x = 35 20x=35 20 x = 35 Dividing both sides by 20: x = 35 20 = 7 4 x=\frac{35}{20}=\frac{7}{4} x = 20 35 ​ = 4 7 ​ Therefore, the correct answer is E.
