Answer:
RATIO
==============================
1. 16 to 4
\implies \large \sf16 \: : \: 4⟹16:4
\implies \large \sf16 \div 4 \: : \: 4 \div 4⟹16÷4:4÷4
\implies \large \sf \orange{4 \: : \: 1}⟹4:1
\:
2. 6 to 15
\implies \large \sf6 \: : \: 15⟹6:15
\implies \large \sf6 \div 3 \: : \: 15 \div 3⟹6÷3:15÷3
\implies \large \sf \orange{2\: : \: 5}⟹2:5
\:
3. 30 : 5
\implies \large \sf30 \: : \: 5⟹30:5
\implies \large \sf30\div 5 \: : \: 5 \div 5⟹30÷5:5÷5
\implies \large \sf \orange{6\: : \: 1}⟹6:1
\:
4. 12/16
\implies \large \sf {12\: : \: 16}⟹12:16
\implies \large \sf {12 \div 4\: : \: 16 \div 4}⟹12÷4:16÷4
\implies \large \sf \orange{3\: : \: 4}⟹3:4
\:
5. 3/8
\implies \large \sf {3\: : \: 8}⟹3:8
\implies \large \sf {3 \div 1\: : \: 8 \div 1}⟹3÷1:8÷1
\implies \large \sf \orange{3\: : \: 8}⟹3:8
