Question

Fill In the Blanks Rational Numbers.​

Answer 1

Answer:

$\frac{ - 3}{7}$

Step-by-step explanation:

let us consider the missing number as x, so

$x \div \frac{3}{7} = - 1 \\ = > x = - 1 \times \frac{3}{7} \\ = > x = \frac{ - 3}{7}$

Hence the missing number is -3/7

$verification \: - > \\ x \div \frac{3}{7} = - 1 \\ = > \frac{ - 3}{7} \div \frac{3}{7} = - 1 \\ = > \frac{ - 3}{7} \times \frac{7}{3} = - 1 \\ = > \frac{ - 3 \times 7}{7 \times 3} = - 1 \\ = > \frac{ - 21}{21} = - 1 \\ = > -1 = -1 \\ = > LHS \: = RHS \:$

hence verified also.

hope it helps.
