Question

If steel – cut oats costs \[\$ 0.58\] per lb, how much would it cost to buy \[\dfrac{1}{2}\] pound?

Answer 1

Hint: Here the question is related to the word problem. Now we have to find the value for the half pound such that they have mentioned the value for the one pound. While solving this problem we use the simple mathematical operations and hence we obtain the required solution for the given question.

Complete step by step solution:
The measurements are different for different forms like solid, liquid and etc., The libra is an ancient Roman unit of mass that was equivalent to approximately 328.9 grams. It was divided into 12 unciae or ounces. The libra is the origin of the abbreviation for pound, "lb". Therefore, the lb means pound itself. The pound is a unit for the measurement of mass.
Now consider the given question
The cost of steel – cuts oats for one pound = \[\$ 0.58\]
The cost of steel – cut oats for a half pound = \[\$ x\]
This can be written as
1 pound = \[\$ 0.58\]
 \[\dfrac{1}{2}\] pound = \[\$ x\]
Now cross multiply the terms and hence we determine the value of x
 \[x = \dfrac{{0.58}}{2}\]
On dividing the number 0.58 by 2 we get
 \[ \Rightarrow x = \$ 0.29\]
Hence, we have determined the solution
Therefore, the cost of half pound steel – cut oats is \[\$ 0.29\]
So, the correct answer is “ \[\$ 0.29\] ”.

Note: This problem is a simple problem where we use the concept of the cross multiplying and hence, we determine the value of unknown. The measurements for different things are different and some of the measuring units will have different names also. In this type of the question we have to write the unit.
