1. The first question asks about the mass $m$ of an elephant rounded to the nearest 1000 kg. This means $m$ is between 5500 and 6500 kg, so we write the inequality $$5500 \leq m < 6500$$. 2. The second question is about the length $L$ of a frog rounded to 1 decimal place. This means $L$ is between 7.35 and 7.85 cm, so we write $$7.35 \leq L < 7.85$$. 3. The third question asks to put calculations in a table based on whether the result is less than, equal to, or greater than 12. 4. The fourth question gives limits on $x$ as $$12.5 \leq x < 13.5$$ and asks what rounding was done. Since the range is from 12.5 to less than 13.5, $x$ was rounded to the nearest whole number. 5. The fifth question asks to fill in missing digits to make division and multiplication correct. In simple terms: - Rounding means the number is close to a certain value within a range. - Inequalities show the possible values the number can have. - When rounding to the nearest 1000 or 1 decimal place, the number lies within a specific interval. - For the table, compare each calculation to 12 to decide where it fits. - For missing digits, find numbers that make the calculations true.
