Solve the following expression:
First we will divide the numerator and the denominator by the highest number that both are divisible by.
In this case, the number is 38.8.
Then, we will divide the fraction as follows:
Write the fraction shown in the picture, in words:
This follows the identity property of division! When any non-zero number is divided by itself, the result is always 1. Think of it this way: how many groups of 38.8 fit into 38.8? Exactly one group!
Yes! Whether it's 5.7 ÷ 5.7, 123.456 ÷ 123.456, or any other decimal, the answer is always 1 when you divide a number by itself (as long as it's not zero).
Still equals 1! When you divide a negative number by the same negative number, you get positive 1. Remember: negative ÷ negative = positive.
You could, but it's unnecessary! Since the numerator and denominator are identical, you can immediately recognize the answer is 1 without any calculations.
That would be undefined! Division by zero is never allowed in mathematics. But 38.8 ÷ 38.8 is perfectly fine since we're not dividing by zero.
