# What number should be subtracted from -2/3 to get -1/6?

For subtracting unlike fractions, take the LCM of the denominators and convert the fractions to equivalent fractions and subtract them as like fractions.

## Answer: -1/2 should be subtracted from -2/3 to get -1/6.

Let's find that number.

**Explanation:**

Let the number which is to be subtracted be x

According to the question,

-2/3 - x = -1/6

x = -2/3 + 1/6 (By transposing terms)

x = (-4 + 1) / 6 (By taking LCM of the denominators)

x = -3/6 or -1/2

### Thus, -1/2 should be subtracted from -2/3 to get -1/6.
