Question

Subtract. (2)/(5d)-(1)/(9d)

Answer 1

To subtract the given fractions, find a common denominator and subtract their numerators.

Step-by-step explanation:

To subtract the given fractions, we need to have a common denominator. In this case, the common denominator is 9d. So, we need to rewrite the fractions with the common denominator:

(2)/(5d) - (1)/(9d) = (18)/(45d) - (5)/(45d)

Now we can subtract the numerators and keep the denominator:

(18 - 5)/(45d) = 13/(45d)

Therefore, the final answer is 13/(45d).
