14512 \frac{1}{4}☐\frac{5}{12}

Video Solution

Solution Steps

00:00 Choose the appropriate sign
00:03 We want to find a common denominator
00:06 Therefore we will multiply the fraction by 3
00:09 Remember to multiply both numerator and denominator
00:17 Now we have a common denominator between the fractions
00:24 When denominators are equal, the larger the numerator, the larger the fraction
00:28 And this is the solution to the question

Step-by-Step Solution

To solve this problem, we'll use the cross-multiplication method to compare the fractions 14 \frac{1}{4} and 512 \frac{5}{12} .

  • Step 1: Cross-multiply the fractions.
    We multiply the numerator of the first fraction by the denominator of the second, and the numerator of the second fraction by the denominator of the first:
  • 1×12=12 1 \times 12 = 12
  • 5×4=20 5 \times 4 = 20
  • Step 2: Compare the results from cross-multiplication.
    Now, compare the results: 12 12 and 20 20 .
    Since 12<20 12 < 20 , it follows that 14<512 \frac{1}{4} < \frac{5}{12} .

Therefore, the correct sign to fill in the blank is < < .

The solution to the problem is 14<512\frac{1}{4} < \frac{5}{12}.
