Definition used: &quot;A rational equation that involves two ratios is called a proportion&quot;. Theorem used: Means-Extremes Theorem &quot;If ab=cd, where b≠0 and d≠0, then ad=bc. Calculation: Consider the proportion a. x2=49 Simplify the proportion x2=49 as follows. x2=49 x⋅9=4⋅2 [Cross multiply] 9x=8 9x9=89 [Divide both the sides with 9] x=89 Consider the proportion b. 2x=94. Simplify the proportion 2x=94 as follows. 2x=94 x⋅9=4⋅2 [Cross multiply] 9x=8 9x9=89 [Divide both the sides with 9] x=89 Consider the proportion c. x4=29 Simplify the proportion x4=29 as follows. x4=29 x⋅9=4⋅2 [Cross multiply] 9x=8 9x9=89 [Divide both the sides with 9] x=89 Consider the proportion d. 92=4x Simplify the proportion 92=4x as follows. 92=4x x⋅9=4⋅2 [Cross multiply] 9x=8 9x9=89 [Divide both the sides with 9] x=89 Consider the proportion e. 49=x2. Simplify the proportion 49=x2 as follows. 49=x2 x⋅9=4⋅2 [Cross multiply] 9x=8 9
