Lesson 5: Fractions and whole numbers

# Representing 1 as a fraction

Let's explore various ways to represent the number 1 as a fraction, like 1/1, 2/2, and 3/3. We see how dividing a whole into equal parts and shading them in can represent 1 whole. We also use a number line to visualize these fractions, emphasizing that they all represent the same value: 1 whole. Created by Sal Khan.

• would 1/1 be considered a fraction?
• Absolutely! 1/1 is a fraction, with 1's in both the numerator and the denominator.
• hi, why is a decimal considered a fraction?
• Because a decimal is part of a whole number like a fraction.
• why is 0/0 unidentified? Why can't 0/0 just equal 0.
• Good question!

If we did 6/2, for example, we would ask ourselves
“what number times 2 is 6?”. The answer would be 3.

In the same way, when we do 0/0, we ask ourselves “what number times 0 is 0?”. Any number times 0 is 0. So 0/0 can be anything and is therefore called indeterminate.

Have a blessed, wonderful day!

• how can a fraction be represented on a number line?
• Fractions exist between whole numbers, so the point representing a fraction would be between two points that represent whole numbers. For example, the fraction 1/2 would be between 0 and 1.

Draw a line and label a point 0 on the far left and another point 1 on the far right. Draw a point in the center of that line between 0 and 1, and write 1/2.
• I am new to fractions. So is 8/8 1 whole?
• Yes - 8/8 is the same thing as 1 - just shown in a different way.

Imagine the pizza. If it was cut into eight slices - 1 slice would be 1/8 of the pizza (1 of the 8 slices) while 8/8 (all 8 slices) would be 1 whole pizza.
• At , "Sal said "one oneth", but meant "one over one".

What is the proper way to say 1/1? One over one, one onethS?
• One over one is correct. I'm sure both can be used (correct me if I'm wrong), but one over one is generally the most universally used.
• would 1/1 be considered a fraction
• Anything counts, unless the denominator is `0`.
So yeah, `1/1` is a fraction. It equals `1` whole

• is o/o a fraction
• `0/0` is indeterminate, it could be equal to any real number but there's no single agreed-upon value for it.
If `0/0 = ?` then that means `0*? = 0`. But we know that anything times `0` equals `0`, so `?` and thus `0/0` could be anything.
