Question

23:134= \frac{2}{3}:1\frac{3}{4}=

Video Solution

Step-by-Step Solution

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

  • Step 1: Convert the mixed number 1341\frac{3}{4} to an improper fraction.

  • Step 2: Replace the division with multiplication by the reciprocal of the improper fraction.

  • Step 3: Perform the multiplication and simplify if necessary.

Now, let's work through each step:
Step 1: Convert 1341\frac{3}{4} to an improper fraction.
A mixed number abca \frac{b}{c} is converted to an improper fraction ac+bc\frac{ac + b}{c}.
So, 134=1×4+34=741\frac{3}{4} = \frac{1 \times 4 + 3}{4} = \frac{7}{4}.

Step 2: Replace the division with multiplication by the reciprocal of 74\frac{7}{4}.
The reciprocal of 74\frac{7}{4} is 47\frac{4}{7}, so the expression becomes: 23×47\frac{2}{3} \times \frac{4}{7}.

Step 3: Perform the multiplication:
Multiply the numerators: 2×4=82 \times 4 = 8.
Multiply the denominators: 3×7=213 \times 7 = 21.
Thus, the product is 821\frac{8}{21}.

No further simplification is needed as 8 and 21 have no common factors.

Therefore, the solution to the problem is 821 \frac{8}{21} .

Answer

821 \frac{8}{21}
