1 1/4 cups of sugar is equals to how many liters if 1 cup is equals to 0.24L? with solution please. Thanks!

1Csugar=.24L

or
1Csugar/.24L=1
or
.24L/1Csugar=1
these are so-called unit conversion factors, so you can use them in multiplying (you dont change an equation if you multiply by 1)
1.25Csugar*(.24L/1Csugar)=1.25*.24 Liter
