Question

if 2/3 x when divided by 1/3 makes 2x write a and if 1/3 x added to 3/9 x makes 6/9 x write b

Answer 1

$\mathtt{ \frac{2}{3} x \: \div \: \frac{1}{3} }$

$\mathtt{ = \frac{2}{3} x \: \times \frac{3}{1} }$

$\mathtt{ = 2x}$

$\blue{ \boxed{ \boxed{ \boxed{ \boxed{ \boxed{a}}}}}}$

$\mathtt{ \frac{1}{3} x \: + \frac{3}{9}}$

$\mathtt{ \frac{3 + 3}{9} x}$

$\mathtt{ = \frac{6}{9}x}$

$\blue{\boxed {\boxed{ \boxed{ \boxed{ \boxed{\mathtt{b}}}}}}}$
