Katyanochek1 [597]
Hello!

5 = 5/1 as a fraction

2/5 × 5/1 = 2

ANSWER:

The product of 2/5 and 5 is greater than 2/5, and less than 5.

Another way you could find out if it's greater or less is by converting the fraction to a decimal and then multiplying it.
You must divide the numerator by the denominator to convert a fraction to a decimal.

2 ÷ 5 = 0.4

0.4 × 5 = 2
