There where ten baked goods in a basket four of them were sold write a fraction to show the part of baked goods that were not sold then write a equivalent fraction to this number

If 4 were sold, then that means 6 were not (10-4=6)

So then we can write 6/10 because 6 were not sold out of a total of 10

Then we can divide the numerator and the denominator by 2 to get 3/5 which is an equivalent fraction
