First, you should find a common denominator:
Turn 2/5 into 4/10 by multiplying by 2.
Then, find the difference in your fractions:
7/10 - 4/10 = 3/10.
Your answer is 3/10.

3% interest on 5,000 = 150
275 (the total amount wanted) - 150 (from initial investment)= 125
x (5%) =125
x (0.05)= 125
x/0.05)= 125/0.05
x=2500
you need to invest 2500 at 5% to get the additional 125
125 plus 150= 275
