Question: How many grams are in \(\dfrac{1}{8}\) of a pound ?...
How many grams are in 81 of a pound ?
Solution
As we know that the above given question is a word problem. A problem is a mathematical question written as one sentence or more describing a real life scenario where that problem needs to be solved by the way of mathematical calculation. To calculate the value in pounds to the value in grams, we just need to multiply the quantity in pounds by the value. We can also apply directly the value and according to the statement just multiply it.
Complete step by step solution:
We need to first understand the requirement of the question which is quantity i.e. grams in
81 of a pound. We know that 1 pound is equal to 453.592grams.
Now according to the question 81 of pound means that 81 of 453.592 i.e.
81×453.592. It gives the value 56.699.
Hence the value in grams in 56.699.
Note: We should always be careful what the question is asking i.e. to find the single unit value or to find the value from a certain number. We should know that in mathematics the term “ of” means to multiply in numbers . Based on the requirement and by observing all the necessary information that is already available in the question we gather the information and then create an equation or by unitary method whichever is applicable, then we solve the problem and then verify the answer by putting the value in the problem and see whether we get the same answer or not.
