Solution Steps

Expand \frac{100.5}{36} by multiplying both numerator and the denominator by 10.

$$\frac{1005}{360}+121\times \frac{6}{36}+144\times \frac{5}{36}+169\times \frac{4}{36}$$

Reduce the fraction \frac{1005}{360} to lowest terms by extracting and canceling out 15.

$$\frac{67}{24}+121\times \frac{6}{36}+144\times \frac{5}{36}+169\times \frac{4}{36}$$

Reduce the fraction \frac{6}{36} to lowest terms by extracting and canceling out 6.

$$\frac{67}{24}+121\times \frac{1}{6}+144\times \frac{5}{36}+169\times \frac{4}{36}$$

Multiply 121 and \frac{1}{6} to get \frac{121}{6}.

$$\frac{67}{24}+\frac{121}{6}+144\times \frac{5}{36}+169\times \frac{4}{36}$$

Least common multiple of 24 and 6 is 24. Convert \frac{67}{24} and \frac{121}{6} to fractions with denominator 24.

$$\frac{67}{24}+\frac{484}{24}+144\times \frac{5}{36}+169\times \frac{4}{36}$$

Since \frac{67}{24} and \frac{484}{24} have the same denominator, add them by adding their numerators.

$$\frac{67+484}{24}+144\times \frac{5}{36}+169\times \frac{4}{36}$$

Add 67 and 484 to get 551.

$$\frac{551}{24}+144\times \frac{5}{36}+169\times \frac{4}{36}$$

Express 144\times \frac{5}{36} as a single fraction.

$$\frac{551}{24}+\frac{144\times 5}{36}+169\times \frac{4}{36}$$

Multiply 144 and 5 to get 720.

$$\frac{551}{24}+\frac{720}{36}+169\times \frac{4}{36}$$

Divide 720 by 36 to get 20.

$$\frac{551}{24}+20+169\times \frac{4}{36}$$

Convert 20 to fraction \frac{480}{24}.

$$\frac{551}{24}+\frac{480}{24}+169\times \frac{4}{36}$$

Since \frac{551}{24} and \frac{480}{24} have the same denominator, add them by adding their numerators.

$$\frac{551+480}{24}+169\times \frac{4}{36}$$

Add 551 and 480 to get 1031.

$$\frac{1031}{24}+169\times \frac{4}{36}$$

Reduce the fraction \frac{4}{36} to lowest terms by extracting and canceling out 4.

$$\frac{1031}{24}+169\times \frac{1}{9}$$

Multiply 169 and \frac{1}{9} to get \frac{169}{9}.

$$\frac{1031}{24}+\frac{169}{9}$$

Least common multiple of 24 and 9 is 72. Convert \frac{1031}{24} and \frac{169}{9} to fractions with denominator 72.

$$\frac{3093}{72}+\frac{1352}{72}$$

Since \frac{3093}{72} and \frac{1352}{72} have the same denominator, add them by adding their numerators.

$$\frac{3093+1352}{72}$$

Add 3093 and 1352 to get 4445.

$$\frac{4445}{72}$$

Factor

$$\frac{5 \cdot 7 \cdot 127}{2 ^ {3} \cdot 3 ^ {2}} = 61\frac{53}{72} = 61.736111111111114$$
