The width of a math textbook is 0.75 inch. How many math textbooks can be placed standing up on a shelf that is 18 inches wide? the answer is 24 hope this help -prestonplayz
18 / (3/4) = 18 * 4 / 3 = 6 * 4 = 24
Didn't need the help, but thanks anyway.
18/(3/4) = 18 * 4/3 = ?
any time
The answer would be 24 like Anonymous and PsyDAG said.
To find the number of math textbooks that can be placed standing up on a shelf, we need to divide the width of the shelf by the width of each textbook.
Given that the width of a math textbook is 0.75 inch and the width of the shelf is 18 inches, we can calculate the number of textbooks as follows:
Number of textbooks = Width of shelf / Width of each textbook
Number of textbooks = 18 inches / 0.75 inch
To divide by a fraction, we can multiply by the reciprocal of that fraction:
Number of textbooks = 18 inches * (1 / 0.75 inch)
Simplifying the fraction, we have:
Number of textbooks = 18 inches * (4 / 3)
Now, multiplying the numbers together:
Number of textbooks = 72 / 3
Number of textbooks = 24
Therefore, 24 math textbooks can be placed standing up on a shelf that is 18 inches wide.
