Answer:
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%
