Tony has 5 bottles each holding 1/4 of juice. Calculate the total quantity of juice he has in millilitres.
1/4 L = 1/4 × 1000/1 = 250
5 bottles = 250mls x 5 =1250mls
Nicholas used 20% of the quantity of juice from a container holding 3.75L to fill 5 identical bottles. Calculate the quantity of juice in each bottle.
1000ml = 1L
3.75 L = 3.75 × 1000 = 3750ml
20% = 20/100 × 3750/1 = 750ml
5 bottles = 750ml
1 bottle = 750 ÷ 5=150ml
