Let's translate each term individually.
1 1/2c can be translated as one and a half times a number. This can also be translated as the product of one and a half and a number.
- 4 can be translated as minus 4 or 4 less than.
11 is translated us just eleven.
So, combining the three translations we have:
One and a half times a number minus four is eleven.
We can also have:
Four less than the product of one and a half and a number is eleven.
Based on the options provided, we might get confused with Option 1 and Option 2. However, if you take a look at Option 1, there's a comma between "one and a half" and "times a number". This makes the equation different. The equation for Option 1 would be 1 1/2 (c - 4) = 11 which is different from the equation that we need to translate.
Hence, the correct translation is Option 2. Four less than the product of one and a half and a number is eleven.
