9/10 times 1/2 subtract 3/10= 9/10 x 1/2 - 3/10= 9/20-3/10= 9/20 - 6/20 = 3/20.
xD.

multiply first so 9/10 times 1/2 =9/20
now 9/20 subtract 3/ 10
we need a common denominator
9/20 subtract 6/20=3/20

[(9/10)*(1/2) - 3/10] =
[9/20 - 3/10] =
[9/20 - 6/20] =
3/20

9/10 x 1/2
= 9/20
9/20 - 3/10 is equal to 9/20 - 6/20
= 3/20

To multiply fractions...
- Take the top times the top to get the new top. 9 times 1 = 9
- Take the bottom times the bottom to get the new bottom. 10 times 2 = 20
The new fraction, therefore, is 9/20.
Now, you need to change the 3/10 to be something over twenty. So multiply the top AND bottom by 2. This is 6/20.
Now you're calculating 9/20 minus 6/20. 9 minus 6 = 3, so you have 3/20.
