3 1/1×5 1/1÷4/4

Answer 1

Let's simplify the expression step by step.

1. Convert mixed numbers to improper fractions:
   • \(3 \frac{1}{1} = 3\)
   • \(5 \frac{1}{1} = 5\)

So the expression becomes: \[ 3 \times 5 \div \frac{4}{4} \]

2. Calculate \(4/4\):

   • \(4/4 = 1\)

3. Now rewrite the expression using this: \[ 3 \times 5 \div 1 \]

4. Perform the multiplication:

   • \(3 \times 5 = 15\)

5. Now divide by 1:

   • \(15 \div 1 = 15\)

Thus, the final answer is: \[ \boxed{15} \]
