What is the difference between 3/4 and 2/10 ?

11 /20

Step-by-step explanation:

Step 1- We can't subtract two fractions with different denominators. So you need to get a common denominator.  

So we multiply 3 by 10, and get 30.

Then we multiply 2 by 4, and get 8.

Next we give both terms new denominators -- 4 × 10 = 40.

So now our fractions look like this:

30 /40 −8/40

Step 2- Since our denominators match, we can subtract the numerators.

30 − 8 = 22

So the answer is:

22 /40

Step 3-

Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction? Yes we can!
