M_{B}=\frac{0.512\times 5\times 10}{0.4}
Cancel out 100 in both numerator and denominator.
M_{B}=\frac{2.56\times 10}{0.4}
Multiply 0.512 and 5 to get 2.56.
M_{B}=\frac{25.6}{0.4}
Multiply 2.56 and 10 to get 25.6.
M_{B}=\frac{256}{4}
Expand \frac{25.6}{0.4} by multiplying both numerator and the denominator by 10.
M_{B}=64
Divide 256 by 4 to get 64.
