What is the answer to your problem?
2/10
2/10 does not equal 2/5.
To solve the expression 9/10 - 2/5, we need to find a common denominator for the fractions.
The common denominator for 10 and 5 is 10.
To convert the fractions so they have the same denominator, we multiply both the numerator and denominator of the first fraction (9/10) by 1 (in the form of 2/2) and we multiply both the numerator and denominator of the second fraction (2/5) by 2.
This gives us:
(9/10) - (2/5) = (9/10) - (4/10)
Now, we can simply subtract the numerators while keeping the same denominator:
(9 - 4) / 10 = 5/10
But 5/10 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 5:
5/10 = 1/2
Therefore, 9/10 - 2/5 is equal to 1/2.
