a box holds 23 puzzles. How many boxes are needed to hold 238 puzzles?
Divide: 238 / 23 = ?
Remember you can't have a part of a box -- so your answer must be a whole number.
To answer this question, we need to find out how many boxes can hold 1 puzzle and then use that information to determine the number of boxes needed for 238 puzzles.
Given that a box holds 23 puzzles, we can set up a proportion to find how many boxes are needed for 1 puzzle:
23 puzzles = 1 box
Now, we need to find how many boxes are needed for 238 puzzles. We can set up an equation using the proportion we just found:
x boxes = 238 puzzles
To solve for x (the number of boxes), we can cross-multiply and then divide:
23 puzzles * x boxes = 1 box * 238 puzzles
23x = 238
Now, divide both sides of the equation by 23 to find the value of x:
x = 238 / 23
Using long division, we find that 238 divided by 23 equals approximately 10.34.
Since we cannot have a fraction of a box, we need to round up to the nearest whole number because we cannot have a fraction of a box. Therefore, we need a total of 11 boxes to hold 238 puzzles.
