Calculating Breakeven with variable cost/ratio

I stumbled upon this question A company is budgeting to sell 200,000 units of it's product next year at a price of $15 per unit. Fixed costs will be $1,232,000 and the variable cost/sales ratio is 44%. What is the breakeven sales revenue and what is the margin of safety in the budge. I know that to calculate BE Revenue I have to divide C/S ratio into Fixed Costs. But I don't understand what variable cost/sales ratio is. I tried to find the C/S ratio from this but I am not getting the the whole concept.
