How to write 7/10-1/2 in the simplest form

1/5

Step-by-step explanation:

Whenever you add or subtract fractions, you must find a common denominator. The denominator is the bottom number in a fraction.

In this case, to find a common denominator, you can multiply 1/2 by 5 on the top and the bottom. This will give you 5/10 which achieves a common denominator.

Now that you have 7/10-5/10 you subtract the numerators and leave the denominators:

7 - 5 = 2

2/10

Now we must simplify this fraction, by dividing the top and the bottom by 2 which gives us 1/5.
