Answer:
25mm : 1 m
Step-by-step explanation:
A ratio is in its simplest form when the second number is 1. To do that here, divide both numbers by 0.48:
[tex]12:0.48\\\\\frac{12}{0.48}=25\\\\\frac{0.48}{0.48}=1\\\\25:1[/tex]
To confirm that its still the same ratio:
[tex]\frac{12}{0.48}=\frac{25}{1}\\\\25=25[/tex]
