3. Volume is the amount of liquid that a container holds. The units of volume of liquid: litre( l ) millilitre(m l ) x 1000  1000 1 l = 1000ml

4. Basic operation involving volumes of liquids Addition and subtraction Make sure that all measurements are in the same units before performing the operations a) 4.95 l – 180 ml = _____________ l 4. 9 5 l -0. 1 8 l 4. 7 7 l 15 8 180 ml = (180  1000) l = 0.18 l 180 ml = (180  1000) l = 0.18 l Same unit

5. b) 6 l 250 ml + 3 l 850 ml= ______ l ______ml 6 l 250 ml + 3 l 850 ml 9 1100 + 1 -1000 10 100  6 l 250 ml + 3 l 850 ml = 10 l 100 ml

6. Multiplication and division a) 5 l 100 ml x 3 = ____________ l 5 l 100 ml x 3 15 l 300 ml 5 l 100 ml x 3 = 15 l 300 ml = 15 l + (300  1000) l = 15 l + 0.3 l = 15.3 l

7. 5.5 l  5 = __________ ml 1. 1 l 5 5. 5 l - 5_______ 5 _____ - 5__ 0 5. 5 l  5 = 1. 1 l = 1. 1 x 1000 ml = 1 100 ml

8. a)2 of 2.1 l=__________ml 3 2 x 2.1 l = 2 x 2.1 l 3 = 2 x 0.7 l =1.4 l = 1.4 x 1000 ml = 1400 ml a)2 of 2.1 l=__________ml 3 2 x 2.1 l = 2 x 2.1 l 3 = 2 x 0.7 l =1.4 l = 1.4 x 1000 ml = 1400 ml 1 0.7 To find the fraction of a given volume, multiply the fraction by the volume of liquid. Or 2 of 2.1 l = 2 x ( 2.1 x1000 ml ) 3 = 2 x 2 100 ml 3 = 1 400 ml Or 2 of 2.1 l = 2 x ( 2.1 x1000 ml ) 3 = 2 x 2 100 ml 3 = 1 400 ml 1 700 Convert the units first and then perform the operation

9. b) 2 2323 2323 x 1 400 ml = 17 7 17 7 x 1 400 ml 1 200 = 3 400 ml = (3 400  1 000) l = 3.4 l = 3 400 ml = (3 400  1 000) l = 3.4 l
