Answer:
The ratios in their simplest form are:
A 25:24
B 19:24
C 23:24
D 11:16
Step-by-step explanation:
The ratios are in their simplest form are the ratios that cannot be simplified further.
We will check all the ratios one by one
<u>A 25:24</u>
Cannot be further simplified so it is in the simplest form
<u>B 19:24</u>
Cannot be simplified further.
<u>C 23:24</u>
Cannot be simplified further
<u>D 11:16</u>
Cannot be simplified further
<u>E 27:18</u>

Further simplified, so it was not in simplest form.
Hence,
The ratios in their simplest form are:
A 25:24
B 19:24
C 23:24
D 11:16
