3 cm

1.5 kg 1.6 ℓ

Example 2
Solve each of the following

(a) ! 20 = ______ m
"

! 20 4 = 8 km
"!
= 8 x 1000 m Convert km to
Cross cancel = 8000 m m

1 km = 1000 m

Example 2
Give the answer, in mixed number

(b) ____ x 120 kg = 320 kg

___ x 120 kg = 320 kg

____ = "#$ %&
'#$ %&

____ = ( Convert to a mixed
" number

____ = 2 #
"

Example 2
Solve the question

(c) 65% of ____ mℓ = 1ℓ 963 mℓ

#" ___ mℓ = 1963 mℓ 1000 mℓ + 963 mℓ
$%% = 1963 mℓ

0.65 x ___ mℓ

1963 mℓ ÷ 0.65 = 3020 mℓ
