Final answer:
The inequality '7 × 6 \u2264 9 × 5' or '42 \u2264 45' represents the sentence 'Seven times six is less than or equal to nine times five', demonstrating the use of an inequality symbol to compare quantities.
Step-by-step explanation:
The inequality that represents the sentence 'Seven times six is less than or equal to nine times five' can be expressed using numbers and an inequality symbol. To represent seven times six, we use '7 × 6', which equals '42'. To represent nine times five, we write '9 × 5', which equals '45'. The phrase 'less than or equal to' is represented by the symbol '\u2264'. Putting these together, the inequality is written as '7 × 6 \u2264 9 × 5' or '42 \u2264 45'. Since 42 is indeed less than or equal to 45, the inequality correctly represents the statement given. This exercise demonstrates how to use an inequality symbol to show how two metric measurements are related, similar to comparing measurements like centimeters and millimeters or meters and kilometers.
