Answer:

1/2 - 2/5= 5/10 - 4/10= 1/10

Step-by-step explanation:

1/2-2/5

first find their least common denominator to get that get the two denominator(the number below the fraction) and factor them, like this

2,4,6,8,10

5,10,15,20

then find their least common factor. (yung parehas nilang factor) you'll see na common factor nila ay 10 right? tht means that's their lcd.

so put it like this n/10- n/10 (n pa ang numerator kasi unknown pa siya)

to find their numerator just divide 10 from the previous denominators then multiply it to the numerator. for example the first fraction is 1/2 so divide mo yung 10 sa 2 then times mo sa 1= 5. yan na yung numerator mo sa first fraction so yung dating 1/2 naging 5/10 na.

next yng isa pang fraction 2/5. so 10÷5 then multiply by 2= 4. that's the numerator for thw second fraction. So yung dating 2/5 became 4/10

so 5/10-4/10= 1/10
