Question

what should be added to -4/5 to get -3/6​

Answer 1

Step-by-step explanation:

Let the number to be added to -4/5 to get -3/6 be x.

So equation = -4/5 + x =-3/6

x= (-3/)6 - (-4/5)

= (-3/6) + 4/5

LCM = 30

(-3/6)= (-15/30)

-4/5=24/30

So -15/30 + 24 /30

(-15 + 24) /30

9 / 30 = 3/10

So checking

-4/5 + 3/10= -3/6

So LCM = 10

-4/5 = -8/10

So = -8/10 + 3/10 = 5/10 = -1/2

We know that -3/6 can be written as -3/6= -1/2

Hence your answer is 3/10

Answer 2

➤ Answer :-

$\dashrightarrow \sf \frac{( - 4)}{5} + (x) = \frac{( - 3)}{6}$

$\dashrightarrow \sf(x) = \frac{( - 3)}{6} - \frac{( - 4)}{5}$

LCM of 6 and 5 is 30.

$\dashrightarrow \sf \frac{( - 3) \times 5}{6 \times 5} - \frac{( - 4) \times 6}{5 \times 6}$

$\dashrightarrow \sf \frac{ (- 15)}{30} - \frac{( - 24)}{30} = \frac{( - 15) - ( - 24)}{30}$

$\dashrightarrow \sf \frac{( - 15) + 24}{30}$

$\dashrightarrow \sf \cancel\frac{9}{30} = \frac{3}{10}$

$\Huge\therefore$$\sf\frac{3}{10}$ should be added to $\sf\frac{-4}{5}$ to get $\sf\frac{-3}{6}$
