Solve (0.4)(0.4-1)(0.4-2)(0.4-3)(-3)/24

$$\frac { ( 0.4 ) ( 0.4 - 1 ) ( 0.4 - 2 ) ( 0.4 - 3 ) ( - 3 ) } { 24 }$$

Evaluate

$$0.1248$$

Solution Steps

Subtract 1 from 0.4 to get -0.6.

$$\frac{0.4\left(-0.6\right)\left(0.4-2\right)\left(0.4-3\right)\left(-3\right)}{24}$$

Multiply 0.4 and -0.6 to get -0.24.

$$\frac{-0.24\left(0.4-2\right)\left(0.4-3\right)\left(-3\right)}{24}$$

Subtract 2 from 0.4 to get -1.6.

$$\frac{-0.24\left(-1.6\right)\left(0.4-3\right)\left(-3\right)}{24}$$

Multiply -0.24 and -1.6 to get 0.384.

$$\frac{0.384\left(0.4-3\right)\left(-3\right)}{24}$$

Subtract 3 from 0.4 to get -2.6.

$$\frac{0.384\left(-2.6\right)\left(-3\right)}{24}$$

Multiply 0.384 and -2.6 to get -0.9984.

$$\frac{-0.9984\left(-3\right)}{24}$$

Multiply -0.9984 and -3 to get 2.9952.

$$\frac{2.9952}{24}$$

Expand \frac{2.9952}{24} by multiplying both numerator and the denominator by 10000.

$$\frac{29952}{240000}$$
