Question

solve for a in the pro
\\(\frac{4}{6} = \frac{6.8}{a}\\)
(a = )
submit

Explanation:

Step1: Cross - multiply the proportion

Given the proportion \(\frac{4}{6}=\frac{6.8}{a}\), cross - multiplying gives us \(4\times a = 6\times6.8\).

Step2: Simplify the right - hand side

Calculate \(6\times6.8 = 40.8\), so the equation becomes \(4a=40.8\).

Step3: Solve for \(a\)

Divide both sides of the equation \(4a = 40.8\) by 4. That is \(a=\frac{40.8}{4}\).
Calculate \(\frac{40.8}{4}=10.2\).

Answer:

\(10.2\)
