Fill in the missing sign:
152☐31
To solve this problem, we'll convert both fractions to have a common denominator and compare:
- Step 1: Identify the denominators (15 and 3) of the fractions 152 and 31.
- Step 2: Find the common denominator. The least common multiple (LCM) of 15 and 3 is 15.
- Step 3: Convert each fraction to have the common denominator 15.
- For 152, the fraction is already over 15, so it stays 152.
- For 31, multiply both the numerator and the denominator by 5 to get an equivalent fraction: 3×51×5=155.
- Step 4: Compare the equivalent fractions 152 and 155.
- Step 5: Since 2<5, it follows that 152<155.
Therefore, the correct sign to fill in the missing slot is <.
Consequently, the completed expression is 152<31.
Therefore, the solution to the problem is <.
