please answer it fast and don't send rubbish answer

and answer it with process and send a pic or write the full answer and explain that how you did this

if u will give rubbish answer then it will be reported with 5 more answers

and try to answer my previous questions​

Answer 1

$\: \: \: \sf : \implies \: \bigg(1 \dfrac{5}{3} \bigg) \times \bigg( \dfrac{1}{4} - \dfrac{1}{9} \bigg) \div \bigg(1 \dfrac{1}{4} \bigg)$

Solving the second bracket :

$\: \: \: \sf : \implies \: \dfrac{1}{4} - \dfrac{1}{9}$

LCM of 4, 9 is 36 :

$\: \: \: \sf : \implies \: \dfrac{1}{4} \times \dfrac{9}{9} = \dfrac{9}{36} \: \: \: \red{ | } \: \: \: \dfrac{1}{9} \times \dfrac{4}{4} = \dfrac{4}{36}$

Subtracting them :

$\: \: \: \sf : \implies \: \dfrac{9 - 4}{36}$

$\: \: \: \sf : \implies \: \dfrac{5}{36}$

Simplifying the first bracket :

$\: \: \: \sf : \implies \: 1 \dfrac{5}{3}$

$\: \: \: \sf : \implies \: \dfrac{3 \times 1 + 5}{3}$

$\: \: \: \sf : \implies \: \dfrac{8}{3}$

Multiplying first and second bracket :

$\: \: \: \sf : \implies \: \bigg( \dfrac{8}{3} \bigg) \times \bigg( \dfrac{5}{36} \bigg)$

$\: \: \: \sf : \implies \dfrac{40}{108}$

On cancellation, we get :

$\: \: \: \sf : \implies \: \dfrac{10}{27}$

Now, we get :

$\: \: \: \sf : \implies \: \bigg( \dfrac{10}{27} \bigg) \div \bigg(1 \dfrac{1}{4} \bigg)$

Simplifying the second bracket now :

$\: \: \: \sf : \implies \: \dfrac{4 \times 1 + 1}{4}$

$\: \: \: \sf : \implies \: \dfrac{5}{4}$

So, the simplified question is :

$\: \: \: \sf : \implies \: \dfrac{10}{27} \div \dfrac{5}{4}$

Multiplying the reciprocal :

$\: \: \: \sf : \implies \: \bigg(\dfrac{10}{27} \bigg) \times \bigg( \dfrac{4}{5} \bigg)$

$\: \: \: \sf : \implies \: \bigg( \dfrac{ \cancel{10}}{27} \bigg) \times \bigg( \dfrac{4}{ \cancel{5}} \bigg)$

$\: \: \: \sf : \implies \: \bigg( \dfrac{2}{27} \bigg) \times ({4} )$

$\: \: \: \sf : \implies \: \dfrac{8}{27}$

Now, the final answer is :

$\boxed{\bf \therefore \:The \: value \: of \: 1 \dfrac{5}{3} \times \bigg( \dfrac{1}{4} - \dfrac{1}{9} \bigg ) \div \bigg(1 \dfrac{1}{4} \bigg ) \: is \: \dfrac{8}{27} .}$

This is the right solution...4/21 is not valid....Check ya' solution again!

Answer 2

15/3+1/4+1/4-11/2

=305/4322

1/2 + 1/2 = 1

1/4/1/4 = 1

bye bye
