Need help solving this proportion:
\[ \frac{x}{4} = \frac{5}{7} \]
Answer (3)
x /4 = 5/7 7 x = 4 ∗ 5 7 x = 20 x = 20/7 x = 2 + 6/7
4 x = 7 5
7 ∗ x = 4 ∗ 5
7 x = 20
x = 2 20 6
x = 2 10 3
To solve the proportion 4 x = 7 5 , we use cross-multiplication, resulting in x = 7 20 , which is approximately 2.857. The steps involve cross-multiplying, isolating x , and simplifying. Thus, the final value of x is about 2.857.
