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
