C=\frac{23\times 73}{75\times 20}-\frac{3}{4}+\frac{\frac{7}{4}\times \frac{1}{2}}{\frac{3}{4}}
Multiply \frac{23}{75} times \frac{73}{20} by multiplying numerator times numerator and denominator times denominator.
C=\frac{1679}{1500}-\frac{3}{4}+\frac{\frac{7}{4}\times \frac{1}{2}}{\frac{3}{4}}
Do the multiplications in the fraction \frac{23\times 73}{75\times 20}.
C=\frac{1679}{1500}-\frac{1125}{1500}+\frac{\frac{7}{4}\times \frac{1}{2}}{\frac{3}{4}}
Least common multiple of 1500 and 4 is 1500. Convert \frac{1679}{1500} and \frac{3}{4} to fractions with denominator 1500.
C=\frac{1679-1125}{1500}+\frac{\frac{7}{4}\times \frac{1}{2}}{\frac{3}{4}}
Since \frac{1679}{1500} and \frac{1125}{1500} have the same denominator, subtract them by subtracting their numerators.
C=\frac{554}{1500}+\frac{\frac{7}{4}\times \frac{1}{2}}{\frac{3}{4}}
Subtract 1125 from 1679 to get 554.
C=\frac{277}{750}+\frac{\frac{7}{4}\times \frac{1}{2}}{\frac{3}{4}}
Reduce the fraction \frac{554}{1500} to lowest terms by extracting and canceling out 2.
C=\frac{277}{750}+\frac{\frac{7\times 1}{4\times 2}}{\frac{3}{4}}
