Answer 2

To solve the expression 2 1/7 × 1.5, we need to convert the mixed number 2 1/7 into an improper fraction.

2 1/7 = (2 × 7 + 1)/7 = 15/7

Now we can multiply the fractions:

(15/7) × 1.5

To multiply fractions, we multiply the numerators together and the denominators together:

(15 × 1)/(7 × 1) × 1.5

= 15/7 × 1.5

Now we can multiply the numerators:

15 × 1 = 15

And multiply the denominators:

7 × 1 = 7

= 15/7 × 1.5

Finally, multiply the numerators:

15 × 1.5 = 22.5

And keep the denominator the same:

= 22.5/7

So, the result of 2 1/7 × 1.5 is 22.5/7.
