Final answer:
To express 2 x 4/5 as the product of a whole number and a unit fraction, multiply 2 by 4 to get 8, which results in 8/5 when placed over the original denominator. Upon dividing 8 by 5, the result can be written as 1 3/5.
Step-by-step explanation:
To write the product of the expression 2 x 4/5 as the product of a whole number and a unit fraction, you simply perform the multiplication of the whole number by the fraction. First, consider the multiplication of 2 and the numerator of the fraction, which in this case is 4. Multiply these two numbers to get a new numerator, then place it over the original denominator to express the result as a fraction.
The calculation looks like this:
2 x 4 = 8, so the product is 8/5.
Now, to represent this as the product of a whole number and a unit fraction, you can divide 8 by 5, which is 1, with a remainder of 3. Thus, you can write the result as 1 3/5, where 1 is the whole number and 3/5 is the unit fraction.
