Answer 2

$Expressing \: the \: ratio \: in \:the \:lowest \\terms : \frac{1.2 \:km }{ 350 \:cm } \\= \frac{ 1.2 \times \blue { 1000 \:m } }{5 \times 7 \times 10 \:cm } \\= \frac{1.2 \times 1000 \times \pink {100 \:cm} }{5 \times 7 \times 10 \:cm }\\= \frac{1.2 \times 20 \times 100 \:cm }{7 \:cm } \\= \frac{ 2400}{7} \\= 2400 : 7$

Therefore.,

$\red { Lowest \:form \:of \: 2\:km : 350 \:cm } \green { = 2400 : 7 }$
