Fill in the missing sign:
125☐87
To solve this problem, we'll follow these steps:
- Step 1: Identify the least common multiple (LCM) of the denominators 12 and 8.
- Step 2: Convert each fraction to have this common denominator.
- Step 3: Compare the converted fractions by examining their numerators.
Let's proceed with the solution:
Step 1: The LCM of 12 and 8 needs to be found. The factorization of 12 is 22×3 and for 8 is 23. The LCM is 23×3=24. Therefore, the common denominator is 24.
Step 2: Convert each fraction to the new denominator:
- Convert 125: The equivalent fraction is found by multiplying both the numerator and the denominator by a number that equals the common denominator when the original denominator is multiplied by it. 24÷12=2. Thus, multiply both the numerator and denominator by 2:
12×25×2=2410.
- Convert 87: Similarly, multiply by 24÷8=3:
8×37×3=2421.
Step 3: Compare the two equivalent fractions 2410 and 2421. Comparing the numerators while the denominators are the same: 10 < 21.
Therefore, 125 is less than 87.
Thus, the correct sign to fill in is <.
