What is 2 equivalent fractions for 1 over 2
Kamila [148]

Answer:

Step-by-step explanation:

1/2

equivalent fractions can be found by multiplying the numerator and denominator by the same number.

1/2 * 2/2 = 2/4....this is equivalent

1/2 * 3/3 = 3/6....so is this one

1/2 * 4/4 = 4/8...this one too

1/2 * 5/5 = 5/10....and this one

I think you get it........and this fraction wont reduce, but if u could reduce it, the reduced fraction would also be equivalent.
