Solution : Consider the number to be X

Given : X × 3/10 = -2/3

∴ 3X/10 = -2/3

By cross multiplying

3X × 3 = -2*10

9X = -20

X = -20/9

∴ The answer is -20/9 should 3/10 be multiplied to get -2/3

Answer 2

Answer:

$\frac{-20}{9}$  must be multiplied by $\frac{3}{10}$  be multiplied to get $\frac{-2}{3}$ .

Step-by-step explanation:

To find : number to be multiplied by $\frac{3}{10}$  be multiplied to get $\frac{-2}{3}$ .

Solution :

• Let , $x$ be the number to be multiplied by $\frac{3}{10}$  be multiplied to get $\frac{-2}{3}$ .
• According to given condition we write as , $\frac{3}{10} \times x = \frac{-2}{3}$
• Using transposition method we find the value of $x$ , by transposing constants at RHS and leaving variables at LHS .

         $\frac{3}{10} \times x = \frac{-2}{3} \\ \\x = \frac{-2}{3} \times \frac{10}{3} \\\\x = \frac{-20}{9}$
