Answer:
5
Explanation:
convert the mixed numbers to fractions:
2 1/2 = 5/2
divide the fractions that are equivalent to multiplication by the reciprocal of the second fraction:
5/2 ÷ 1/2 would = 5/2 x 2/1
once rearranged, multiply all of the numerators by each other. do the same with the denominators and form a new fraction with these values:
5x2 = 10
2x1 = 2
--
10/2
the GCF of 10 and 2 is 2. the result can be simplified by dividing both the numerator and denominator by 2
10÷2=5
OR, in simpler, picture above :)
