Learning to solve division problems where the divisor is unknown can be a little tricky at first. Consider the problem 82 divided by what equals 68. The unknown 'what' can be replaced with a variable. Mathematicians often use 'x' as the common variable. So in this case, the problem can be rephrased as: What is the value of x such that 82 divided by x equals 68?
To solve this type of problem, you could set up an equation as: \[ \frac{82}{x} = 68 \] Then, to isolate x, multiply both sides of the equation by x: \[ 82 = 68x \] Next, to find the value of x, divide both sides by 68: \[ x = \frac{82}{68} \]
If the answer to the problem isn't a whole number, consider rounding it to three decimal places. For this particular problem, the answer would be approximately 1.206.
To master this technique, you can try with some other problems. For example: - What divided by 12 equals 1? - 68 divided by what equals 79? - What is 1/18 divided by 26? - What is 14/7 divided by 15/12? - What is 63 divided by 17/8?
