$$(0.45+0.06+0.69+0.32+0.69+0.32+0.99+0.71) \times 400 \div 4$$

Evaluate

$$423$$

Solution Steps

Add 0.45 and 0.06 to get 0.51.

$$\frac{\left(0.51+0.69+0.32+0.69+0.32+0.99+0.71\right)\times 400}{4}$$

Add 0.51 and 0.69 to get 1.2.

$$\frac{\left(1.2+0.32+0.69+0.32+0.99+0.71\right)\times 400}{4}$$

Add 1.2 and 0.32 to get 1.52.

$$\frac{\left(1.52+0.69+0.32+0.99+0.71\right)\times 400}{4}$$

Add 1.52 and 0.69 to get 2.21.

$$\frac{\left(2.21+0.32+0.99+0.71\right)\times 400}{4}$$

Add 2.21 and 0.32 to get 2.53.

$$\frac{\left(2.53+0.99+0.71\right)\times 400}{4}$$

Add 2.53 and 0.99 to get 3.52.

$$\frac{\left(3.52+0.71\right)\times 400}{4}$$

Add 3.52 and 0.71 to get 4.23.

$$\frac{4.23\times 400}{4}$$

Multiply 4.23 and 400 to get 1692.

$$\frac{1692}{4}$$

Divide 1692 by 4 to get 423.

$$423$$

Factor

$$47\times 3^{2}$$
