Step-by-Step Solution

To solve the division 610÷25 \frac{6}{10} \div \frac{2}{5} , we use the method of multiplying by the reciprocal of the divisor.

First, identify the reciprocal of the divisor 25 \frac{2}{5} . The reciprocal is obtained by swapping the numerator and denominator, resulting in 52 \frac{5}{2} .

Next, replace the division operation with multiplication by the reciprocal:

610×52 \frac{6}{10} \times \frac{5}{2} .

Now, perform the multiplication of the fractions by multiplying numerator by numerator and denominator by denominator:

6×510×2=3020 \frac{6 \times 5}{10 \times 2} = \frac{30}{20} .

Simplify the fraction 3020 \frac{30}{20} by finding the greatest common divisor. Both 30 and 20 can be divided by 10:

30÷1020÷10=32 \frac{30 \div 10}{20 \div 10} = \frac{3}{2} .

The simplified fraction 32 \frac{3}{2} can also be expressed as a mixed number:

112 1\frac{1}{2} .

Therefore, the solution to the problem 610÷25 \frac{6}{10} \div \frac{2}{5} is 112 1\frac{1}{2} , aligning with choice 1.

Answer

112 1\frac{1}{2}
