Question

328134= 3\frac{2}{8}-1\frac{3}{4}=

Video Solution

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Convert 1341\frac{3}{4} to a fraction with a denominator of 8.
  • Step 2: Subtract the whole numbers and fractions separately.
  • Step 3: Simplify the resulting fraction and combine it with the whole number part.

Now, let's work through each step:

Step 1: Convert 1341\frac{3}{4} to a fraction with a denominator of 8.
Since 34=68 \frac{3}{4} = \frac{6}{8} (by multiplying numerator and denominator by 2), we have:
134=1+68=88+68=1481\frac{3}{4} = 1 + \frac{6}{8} = \frac{8}{8} + \frac{6}{8} = \frac{14}{8}.

Step 2: Subtract the whole numbers and fractions separately.
Original problem: 328134=2681483\frac{2}{8} - 1\frac{3}{4} = \frac{26}{8} - \frac{14}{8}.

Subtract the fractions:
268148=128\frac{26}{8} - \frac{14}{8} = \frac{12}{8}.

Step 3: Simplify the resulting fraction and combine it with the whole number part.
128=32\frac{12}{8} = \frac{3}{2}.

Therefore, after subtracting and simplifying, we find that:

Therefore, the solution to the problem is 112 1\frac{1}{2} .

Answer

112 1\frac{1}{2}
