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

Explanation:

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

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.

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

Summary:

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