40%
Because, 2/5 equals 4/10. 10x10=100, so 4x10=40, so 40%.
multiply 3.5 x 3 = 10.5
add -5 +-10 = -15
so you have 10.5 x 10^15
then you need to move the decimal point 1 place to the left to get 1.05
since you move the decimal point 1 place to the left you add 1 to the -15 to get -14
so answer = 1.05 x 10^-14
