Which value is least 0.1 or 2/5 or 3/4

0.1

Step-by-step explanation:

Think about each number as a part of 100.

so 0.1 = 10% of 100

2/5 = 40% of 100, because if you divide 100 by the denominator (5), you get that 1/5 is equal to 20% of 100. So 20+20 is 40%

3/4= 75% of 100, because if you divide 100 by the denominator (4), you get that 1/4 is equal to 25% of 100. So 25+25+25 is 75%
