Question

One third of marbles is 7 , therefore it's two third is ---------

Answer 1

Answer:

Let the marbles be x

From given,

$(1 \div 3) \times x = 7$

$x = 7 \times 3$

$x = 21$

Now the question is two third of marbles =?

Therefore,

$(2 \div 3) \times x = (2 \div 3) \times 21$

Since x = 21

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 2 \times 7$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: (2 \div 3) \times x = 14$

Hence two third of marbles is 14
