Step 1 : l Simplify — a Equation at the end of step 1 : l — - lwh = 0 a Step 2 :Rewriting the whole as an Equivalent Fraction : 2.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using a as the denominator : lwh lwh • a lwh = ——— = ——————— 1 a L (liter) : A = 1 H L W (henry liter watt)
A = L · W · H / : WH
L = A/ W H so c is the answer
