The amount of juice needed is #31.5L#

Explanation:

If each glass is filled to #350 ml#, and there are #450# glasses,

Total volume of liquid #TV=350ml*450 = 157500ml#

#TV# is also represented by #5# which is the sum of the ratio of #4:1# water to juice.

To find the quantity of water to juice we will then need to divide the #TV# by #5# then multiply by the proportion defined by the ratio.

#(157500ml)/5 = 31500ml#

The amount of juice used is then: #31500ml xx 1 = 31500ml#

Juice = #31500ml = 31.5l#

#31.5# litres

Explanation:

Find the total volume first:

#450# glasses each contain #350# ml

#450 xx 350 = 157,500# ml.

Convert to litres immediately (#div 1000#)

#157,500 div 1000 =157.5# litres

The ratio: #" water : juice "# is #" "4" : "1#

This means that #4/5# is water and only#1/5# is juice.

The volume of juice is therefore:

#1/5 xx 157.5 = 31.5# litres
