Answer 1

Question :

• A number when multiplied by 13/3 gives 39/12 ..Find the number.

To find :

• when multiplied by 13/3 gives 39/12 ..Find the number

Let's start :

Let the required number be = x

according to the question

$\: \: \: \: \: \: \: \boxed{ \tt \frac{13}{3} \times x = \frac{39}{12} }$

$\: \: \: \: \: \: \: \: \boxed{ \tt \: x = \frac{39}{12} \div \frac{13} {3} }$

$\: \: \: \: \: \: \: \: \boxed{ \tt \: x = \frac{ \cancel{39}}{12} \div \frac{3}{ \cancel{13}} }$

$\: \: \: \: \: \: \: \: \boxed{ \tt \: x = \frac{3}{ \cancel{12}} \div \frac{ \cancel3}{1} }$

$\: \: \: \: \: \: \: \: \: \: \: \boxed{ \tt\red{x = \frac{3}{4} }}$

$\tt \: The \: required \: no. \: is = \boxed{ \tt \frac{3}{4} }$

Answer 2

Answer:

Let the number be x

From question,

x *13/3 = 39/12

=>13x/3 = 39/12

=>13x*12=39*3

.

. . x= (39*3)/(13*12)

=3/4
