Question

40:52 +6.76.5+ 25:5.9​

Answer 1

Ответ:  40:52 +6.7

        сначала делим 40:52 получается обыкновенная дробь   $\frac{40}{52}$ можно ее сократить получается  $\frac{40}{52} =\frac{10}{13}$

потом додаем 6.7 ее мы тоже переводим в обыкновенную дробь потомучто $\frac{10}{13}$ невозмжно перевести в десятичную дробь

$\frac{10}{13} +6.7=\frac{10}{13} +6\frac{7}{10} =\frac{100}{130} +6\frac{91}{130} =7\frac{61}{130}$

$6.5+25$÷$5.9$$=6.5+25$÷$5\frac{9}{10}$=$6.5+25$÷$\frac{59}{10} =6.5+25$×$\frac{10}{59}$=$6.5+\frac{250}{59} =6.5+4\frac{14}{59} =6\frac{5}{10} +4\frac{14}{59} =6\frac{1}{2} +4\frac{14}{59} =6\frac{59}{118} +4\frac{28}{118} =10\frac{87}{118}$

Answer 2

It seems like you're trying to add some time values together, but the format you've used is a bit unclear. The standard format for representing time is hours:minutes:seconds. Could you please provide the values in that format so I can help you perform the addition accurately? For example, instead of "40:52", you would have hours, minutes, and seconds like "40 hours, 52 minutes, 0 seconds".
