14/20 minus 3/5 is 1/10
9/10 minus 1/10 is 4/5
10 to the power of minus 1 is equal to 1 divided by 10, which is 0.1. This can be calculated by taking the reciprocal of 10 raised to the power of 1, which is 10. Therefore, 10 to the power of minus 1 is equivalent to 0.1.
2/5 = 4/10 minus 1/10 is 3/10
1 over 2
