Solve 45*0.05+55*0.18+65*0.28+75*0.26+58*0.17+95*0.06

$$45 \times 0.05+55 \times 0.18+65 \times 0.28+75 \times 0.26+58 \times 0.17+95 \times 0.06$$

Evaluate

$$65.41$$

Solution Steps

Multiply 45 and 0.05 to get 2.25.

$$2.25+55\times 0.18+65\times 0.28+75\times 0.26+58\times 0.17+95\times 0.06$$

Multiply 55 and 0.18 to get 9.9.

$$2.25+9.9+65\times 0.28+75\times 0.26+58\times 0.17+95\times 0.06$$

Add 2.25 and 9.9 to get 12.15.

$$12.15+65\times 0.28+75\times 0.26+58\times 0.17+95\times 0.06$$

Multiply 65 and 0.28 to get 18.2.

$$12.15+18.2+75\times 0.26+58\times 0.17+95\times 0.06$$

Add 12.15 and 18.2 to get 30.35.

$$30.35+75\times 0.26+58\times 0.17+95\times 0.06$$

Multiply 75 and 0.26 to get 19.5.

$$30.35+19.5+58\times 0.17+95\times 0.06$$

Add 30.35 and 19.5 to get 49.85.

$$49.85+58\times 0.17+95\times 0.06$$

Multiply 58 and 0.17 to get 9.86.

$$49.85+9.86+95\times 0.06$$

Add 49.85 and 9.86 to get 59.71.

$$59.71+95\times 0.06$$

Multiply 95 and 0.06 to get 5.7.

$$59.71+5.7$$

Add 59.71 and 5.7 to get 65.41.

$$65.41$$

Factor

$$\frac{31 \cdot 211}{2 ^ {2} \cdot 5 ^ {2}} = 65\frac{41}{100} = 65.41$$
