Explain why 1/2 is not equivalent to 2/5.
Find ing the common denominator would make it 10.for 1/2 to get to 10 you have to multiply by 51/2x5= 5/10then you have to convert 2/5 to get the denominator to be 10so you multiply 2/5 by 22/5x2= 4/105/10 is greater than 4/10
1/2 = 50%2/5 = 40%50% is more than 40%
