Question

What should be added to 2/5 to get (-3/2)?​

Answer 1

Answer:

-19/10

Step-by-step explanation:

Let number to be added x

2/5+x= -3/2

x = -3/2 -2/5

x = -15 - 4/10

x = -19/10

Answer 2

Step-by-step explanation:

Let

❥ The number = x

➵ x + $\frac{ 2 }{ 5 }$ = $\frac{ -3 }{ 2 }$

➵ x = ($\frac{ -3 }{ 2 }$) - ($\frac{2}{5}$

• LCM of 2 and 5 = 2 × 5 = 10

➵ x = $\frac{ (-3 \: × \: 5) \: - \: (2 \: × 2)}{ 10 }$

➵ x = $\frac{ (-15 \: - \: 4) }{ 10 }$

➵ x = $\frac{ (-19) }{ 10 }$

➵ $\large\fbox\green{ x \: \: = \: \: -1.9 }$

P R O O F :-

❥LHS = x + $\frac{ 2 }{ 5 }$

• -1.9 + 0.4
• -1.5 Or $\frac{ -3 }{ 2 }$
