Hey there!
Basically a “ratio” is the outcome of expressions in mathematics. Whereas, “rate” is the 2 amount of different units that’s being compared as your given ratios
Example of the two:
Ratio:
4:2
= 4 / 2
= 4 ÷ 2
Rate:
60 second per minute
= 60 seconds / 1
= 1 minute
Good luck on your assignment and enjoy your day!
