Ответ:
6.75
Step-by-step explanation:
Since, when we rounded a decimal number to 2 significant figures,
We check the thousandth digit, ( third digit after decimal )
If thousandth digit is less than 5 then the hundredth digit ( second digit after decimal ) will be rounded to preceding number while if it is 5 or more than 5 then the hundredth digit will be rounded to succeeding number,
∵ 9 > 5
Hence, 6.7493 ≈ 6.75
