Josh says that 2/3 is always the same as 4/6. Meghan says that 2/3 and 4/6 are equivalent fractions, but they could be different amounts. Which student is correct?
I say Josh.
I say Josh.
I'm taking Meghan to be correct. Josh can have 2 slices out of 3 in a single pie, but Meghan could have 4/6 (4 slices out of 6) of two pies.RTCNTC said:Josh says that 2/3 is always the same as 4/6.

That's the only thing I can think of.

This is what they are teaching US 3rd graders, folks. God help us all.

Equivalent fractions are fractions that represent the same value, even though they may look different. They have different numerators and denominators, but they are equal to each other.
To find equivalent fractions, you can multiply or divide both the numerator and denominator by the same number. For example, to find an equivalent fraction to 1/2, you can multiply both the numerator and denominator by 2 to get 2/4.
Equivalent fractions are useful because they help us compare and order fractions. They also help us simplify fractions and make working with fractions easier.
Yes, all fractions can be equivalent. As long as you multiply or divide both the numerator and denominator by the same number, the resulting fraction will be equivalent.
A visual model, such as a fraction bar or a pie chart, can help you understand equivalent fractions by showing you how different fractions represent the same amount. For example, 1/2 and 2/4 may look different on paper, but they both represent half of a whole when shown in a visual model.
