Thrice divided by y minus 12 multiply by m

"Thrice divided by y" is gibberish. However,

Three divided by y = 3/y
Now you get murky. The result could be either
(3/y - 12)*m
or
3/y - 12*m
or even
3/(y-12) * m
or 3/((y-12)*m)

I suspect it is supposed to be 3/y - 12m

To evaluate the expression "thrice divided by y minus 12 multiplied by m", we need to follow the order of operations, also known as PEMDAS.

1. Start with the given expression: (3/y - 12) * m.

2. Begin by evaluating "thrice divided by y": 3/y. This means dividing 3 by the value of y.

3. Next, subtract 12 from the result obtained in step 2: (3/y - 12).

4. Finally, multiply the result from step 3 by the value of m: (3/y - 12) * m.

In summary, the expression "thrice divided by y minus 12 multiplied by m" can be evaluated using the order of operations as outlined above.
