Q.

$huge color{pink}{underbrace{textsf{textbf{ color{black}↓{color{silver}{P}{color{pink}{e}{color{silver}{n}{color{pink}{y}{color{silver}{e}{color{pink}{l}{color{silver}{e}{color{pink}{s}{color{silver}{a}{color{pink}{i}{color{silver}{a}{color{pink}{n}{ color{blvak}↓}}}}}}}}}}}}}}}}}$

$1. : frac{8}{4} - frac{6}{2} times frac{5}{1}$

${ {{colorbox{yell}{ = (8 ÷ 4) - (6 ÷ 2) × (5 ÷ 1)}}}}$

${ {{colorbox{yell}{ = 2 - (3 × : 5) }}}}$

${ {{colorbox{yell}{ = 2 - 15}}}}$

${ {{colorbox{yell}{ = - 13}}}}$

____________________________

${ {{colorbox{yell}{2. : (2.4 + 3.5) - 2.3}}}}$

$= 5 frac{9}{10} - 2.3$

$= frac{36}{10} = frac{18}{5} = 3 frac{3}{5} => 3,6$

1.)

$frac{8}{4} - frac{6}{2} times frac{5}{1} = \ \ = frac{8}{4} - frac{6}{2} times frac{5}{1} \ = 2 - frac{6}{2} times frac{5}{1} \ = 2 - 15 \ = - 13 \ = - 13$

2.)

$2.4 + 3.5 - 2.3 \ \ =( 2.4 + 3.5) - 2.3 \ = (5.9 - 2.3) \ = 3.6 \ \ = 3.6$
