Hi everyone. I'm going to be teaching comparing fractions soon and I had a quick question about equivalent fractions. When comparing fractions such as 2/4 and 4/8, would I use a regular equal sign or the wavy equal sign? It's been a while :haha: Thanks!

Equals.
Equivalent MEANS equal.

A 'wavy' equal sign (really an equals sign with a tilde like wave above) means 'approximately'.

Side note: the equal sign with the tilde is most commonly used in geometry and denotes congruency between shapes.
