Answer:

19/20

Step-by-step explanation:

7/10+1/4

LCM of 10 and 4 is 20,

denominator is 20

10 x 2 is 20 and 4 x 5 is 20

so we have to do 7 x 2 and 1 x 5

14/20 + 5/20 = 19/20
Make the denominator the same they both can be 20.
So one will be 14/20 and one will be 5/20
So now you can add straight across the top only so it would be 19/20
Good luck
