let us subtract
\(\dfrac{ 5}{6} – \dfrac{-2}{3}\)
By taking LCM for 6 and 3 which is 6
\(\dfrac{ 5}{6} –\dfrac{ -2}{3} \)
\( = \dfrac{(5×1)}{(6×1)} – \dfrac{(-2×2)}{(3×2)} \)
\( = \dfrac{5}{6} – \dfrac{-4}{6}\)
Since the denominators are same we can subtract directly
\(\dfrac{ (5+4)}{6} =\dfrac{ 9}{6}\)
Further we can divide by 3 we get,
\(\dfrac{ 9}{6} =\dfrac{3}{2}\)
Answered by Aaryan | 1 year agoBy what number should 1365 be divided to get 31 as quotient and 32 as remainder?
Which of the following statement is true / false?
(i) \(\dfrac{ 2 }{ 3} – \dfrac{4 }{ 5}\) is not a rational number.
(ii) \( \dfrac{ -5 }{ 7}\) is the additive inverse of \( \dfrac{ 5 }{ 7}\)
(iii) 0 is the additive inverse of its own.
(iv) Commutative property holds for subtraction of rational numbers.
(v) Associative property does not hold for subtraction of rational numbers.
(vi) 0 is the identity element for subtraction of rational numbers.
If x = \( \dfrac{4 }{ 9}\), y =\( \dfrac{-7 }{ 12}\) and z = \( \dfrac{-2 }{ 3}\), then verify that x – (y – z) ≠ (x – y) – z
If x = \(\dfrac{ – 4 }{ 7}\) and y = \( \dfrac{2 }{ 5}\), then verify that x – y ≠ y – x
Subtract the sum of \(\dfrac{ – 5 }{ 7} and\dfrac{ – 8 }{ 3}\) from the sum of \(\dfrac{5 }{ 2} and \dfrac{– 11 }{ 12}\)
