9/20
3/7
18/40

but i choose 9/20 is that correct?

Yes you are correct. 9/20 is correct.

Step-by-step explanation:

7 /10   - 1 /4  =  

7 * 2 / 10*2  

1 * 5  / 4 * 5  = 14 /20  -5 /20   =9 /20

yes you are correct

Step-by-step explanation:   7/10 - 1/4 = 9/20

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
