Solution Steps

Reduce the fraction \frac{90}{100} to lowest terms by extracting and canceling out 10.

$$80\times \frac{9}{10}+85\times \frac{60}{100}+125+140+115+80\times \frac{30}{100}+75\times \frac{30}{100}+30+20+25$$

Express 80\times \frac{9}{10} as a single fraction.

$$\frac{80\times 9}{10}+85\times \frac{60}{100}+125+140+115+80\times \frac{30}{100}+75\times \frac{30}{100}+30+20+25$$

Multiply 80 and 9 to get 720.

$$\frac{720}{10}+85\times \frac{60}{100}+125+140+115+80\times \frac{30}{100}+75\times \frac{30}{100}+30+20+25$$

Divide 720 by 10 to get 72.

$$72+85\times \frac{60}{100}+125+140+115+80\times \frac{30}{100}+75\times \frac{30}{100}+30+20+25$$

Reduce the fraction \frac{60}{100} to lowest terms by extracting and canceling out 20.

$$72+85\times \frac{3}{5}+125+140+115+80\times \frac{30}{100}+75\times \frac{30}{100}+30+20+25$$

Express 85\times \frac{3}{5} as a single fraction.

$$72+\frac{85\times 3}{5}+125+140+115+80\times \frac{30}{100}+75\times \frac{30}{100}+30+20+25$$

Multiply 85 and 3 to get 255.

$$72+\frac{255}{5}+125+140+115+80\times \frac{30}{100}+75\times \frac{30}{100}+30+20+25$$

Divide 255 by 5 to get 51.

$$72+51+125+140+115+80\times \frac{30}{100}+75\times \frac{30}{100}+30+20+25$$

Add 72 and 51 to get 123.

$$123+125+140+115+80\times \frac{30}{100}+75\times \frac{30}{100}+30+20+25$$

Add 123 and 125 to get 248.

$$248+140+115+80\times \frac{30}{100}+75\times \frac{30}{100}+30+20+25$$

Add 248 and 140 to get 388.

$$388+115+80\times \frac{30}{100}+75\times \frac{30}{100}+30+20+25$$

Add 388 and 115 to get 503.

$$503+80\times \frac{30}{100}+75\times \frac{30}{100}+30+20+25$$

Reduce the fraction \frac{30}{100} to lowest terms by extracting and canceling out 10.

$$503+80\times \frac{3}{10}+75\times \frac{30}{100}+30+20+25$$

Express 80\times \frac{3}{10} as a single fraction.

$$503+\frac{80\times 3}{10}+75\times \frac{30}{100}+30+20+25$$

Multiply 80 and 3 to get 240.

$$503+\frac{240}{10}+75\times \frac{30}{100}+30+20+25$$

Divide 240 by 10 to get 24.

$$503+24+75\times \frac{30}{100}+30+20+25$$

Add 503 and 24 to get 527.

$$527+75\times \frac{30}{100}+30+20+25$$

Reduce the fraction \frac{30}{100} to lowest terms by extracting and canceling out 10.

$$527+75\times \frac{3}{10}+30+20+25$$

Express 75\times \frac{3}{10} as a single fraction.

$$527+\frac{75\times 3}{10}+30+20+25$$

Multiply 75 and 3 to get 225.

$$527+\frac{225}{10}+30+20+25$$

$$527+\frac{45}{2}+30+20+25$$

Convert 527 to fraction \frac{1054}{2}.

$$\frac{1054}{2}+\frac{45}{2}+30+20+25$$

Since \frac{1054}{2} and \frac{45}{2} have the same denominator, add them by adding their numerators.

$$\frac{1054+45}{2}+30+20+25$$

Add 1054 and 45 to get 1099.

$$\frac{1099}{2}+30+20+25$$

Convert 30 to fraction \frac{60}{2}.

$$\frac{1099}{2}+\frac{60}{2}+20+25$$

Since \frac{1099}{2} and \frac{60}{2} have the same denominator, add them by adding their numerators.

$$\frac{1099+60}{2}+20+25$$

Add 1099 and 60 to get 1159.

$$\frac{1159}{2}+20+25$$

Convert 20 to fraction \frac{40}{2}.

$$\frac{1159}{2}+\frac{40}{2}+25$$

Since \frac{1159}{2} and \frac{40}{2} have the same denominator, add them by adding their numerators.

Add 1159 and 40 to get 1199.

$$\frac{1199}{2}+25$$

Convert 25 to fraction \frac{50}{2}.

$$\frac{1199}{2}+\frac{50}{2}$$

Since \frac{1199}{2} and \frac{50}{2} have the same denominator, add them by adding their numerators.

$$\frac{1199+50}{2}$$

Add 1199 and 50 to get 1249.

$$\frac{1249}{2}$$

Factor

$$\frac{1249}{2} = 624\frac{1}{2} = 624.5$$
