Answer 1

Ответ:

1)= 648×475:152=2025

2)=816×502:204=2008

3)=(8+280): 16= 288:16= 18

4)=288×703:144=1406

Answer 2

$648$ × $475$ ÷ $(1458 - 1306) = 648$ × $475$ ÷ $152 = 307800$ ÷ $152 = 2025$

$816$ × $502$ ÷ $(85117 - 84913) = 816$ × $502$ ÷ $204 = 409632$ ÷ $204 = 2008$

$(912$ ÷ $114 + 6440$ ÷ $23)$ ÷ $16 = (8 + 6440$ ÷ $23)$ ÷ $16 = (8 + 280)$ ÷ $16 = 288$ ÷ $16 = 18$

$288$ × $703$ ÷ $(405060 - 404916) = 288$ × $703$ ÷ $144 = 202464$ ÷ $144 = 1406$

Ответы: $2025$; $2008$; $18$; $1406$.
