Answer 2

Calculation: 1 7/10 * 2 1/2

To calculate the product of 1 7/10 and 2 1/2, we can convert the mixed numbers to improper fractions and then multiply them.

1 7/10 can be written as an improper fraction as follows: 1 7/10 = (1 * 10 + 7)/10 = 17/10

2 1/2 can be written as an improper fraction as follows: 2 1/2 = (2 * 2 + 1)/2 = 5/2

Now, we can multiply the two fractions:

(17/10) * (5/2) = (17 * 5)/(10 * 2) = 85/20

To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 5:

85/20 = (85/5) / (20/5) = 17/4

Therefore, 1 7/10 * 2 1/2 is equal to 17/4.
