Fractions and decimals are related in a very close way. Ways such as they are both representing a whole number. 

for example 

1/2 , 0.5 , 50% 

all three numbers have the same value but are expressed in a different format. all three represent the same whole number. 

another example would be

1/4 , 0.25 , 25% 

hopefully this helped. and or makes sense. 

LET ME KNOW :p
