Multiply top and bottom by the same number
2/3 and 8/12 are equal because both the numerator and the denominator were multiplied by 4. Ask: what was the bottom multiplied by? Then do the same to the top.
Why it matters
Equivalent fractions let students compare fractions with different denominators and add them — so it is worth getting fluent here first.
