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

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 l l l ml = (180  1000) l = 0.18 l 180 ml = (180  1000) l = 0.18 l Same unit

b) 6 l 250 ml + 3 l 850 ml= ______ l ______ml 6 l 250 ml + 3 l 850 ml  6 l 250 ml + 3 l 850 ml = 10 l 100 ml

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 l = 15.3 l

5.5 l  5 = __________ ml 1. 1 l l - 5_______ 5 _____ - 5__ l  5 = 1. 1 l = 1. 1 x 1000 ml = 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 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 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 ml 3 = ml Or 2 of 2.1 l = 2 x ( 2.1 x1000 ml ) 3 = 2 x ml 3 = ml Convert the units first and then perform the operation

b) x ml = x ml = ml = (3 400  1 000) l = 3.4 l = ml = (3 400  1 000) l = 3.4 l
