Question

sinplif :17/20 - 13/25​

Answer 1

Answer:

33/100

Step-by-step explanation:

LCM of the denominators i.e. 20 and 25 = 100

ln 17/20 , we need to multiply 5 to 20 to make it 100

and in 13/25 , we need to multiply 4 to 25 to make it 100.

As we know, we multiply the same number to the numerator as the denominator .

So 17×5/20×5 and 13×4/25×4

Now , we have 85/100 and 52/100

So now, we will do as per the question i.e. 85/100 - 52/100

85-52= 33

So answer is 33/100
