A 1-lb mixture of nuts contains 11 oz of cashews and 5 oz of peanuts.  What is the ratio of cashews to peanuts?

This is a math question. May I ask, when writing a ratio, do we need to write only the number?  Or also the unit?  Ex: (oz)together with the number?

A ratio is just a comparison.  You are comparing the amount of one thing TO the amount of the other.  Because the numbers you are comparing are in the same unit - ounces - this is very straight-forward. 

First, you need to examine the question.  It is asking the ratio of cashews to peanuts.  Based on your information, there are

11 oz of cashews TO 5 oz of peanuts.

11 : 5 (no need to express the unit)

This could also be expressed as a fraction:  11/5.  Always look at your ratio as a fraction, and see if you can reduce it.  11/5 can not be reduced, so the ration remains 11:5.

However, if the ratio had been 12:6, then the fraction 12/6 could be reduced to 2/1 - the reduced ratio would then be 2:1.

Remember, though, that your example can not be reduced.

You do not need to write the unit, if you are asked for a ratio.  It is 11:5, cashews to peanuts (by weight).  If you had 16 pounds of nuts with 11 lbs. cashews and 5 lbs peanuts, the ratio would still be 11:5.

The ratio would be 11:5 to its simplest term.

Don't care about the units, just write the quantity of the nuts inside the ration a:b. Also, don't care about the mass of the nuts, it has no effect on the ratio
