5 - \dfrac{3}{7} = 4 \dfrac{4}{7}

We start by subtracting the fractions:

\dfrac{5}{1} - \dfrac{3}{7}

To subtract fractions, we need to have a common denominator. In this case, the common denominator is 7.

So, we need to convert the whole number 5 into a fraction with a denominator of 7:

5 = \dfrac{5}{1} \times \dfrac{7}{7} = \dfrac{35}{7}

Now we can subtract the fractions:

\dfrac{35}{7} - \dfrac{3}{7} = \dfrac{35-3}{7} = \dfrac{32}{7}

Now we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 1 in this case:

\dfrac{32}{7} = \dfrac{32 \div 1}{7 \div 1} = \dfrac{32}{7}

So, the answer is 4 \dfrac{4}{7}.

Next,

12 - \dfrac{8}{17} = 11 \dfrac{9}{17}

To subtract fractions, we need to have a common denominator. In this case, the common denominator is 17.

So, we need to convert the whole number 12 into a fraction with a denominator of 17:

12 = \dfrac{12}{1} \times \dfrac{17}{17} = \dfrac{204}{17}

Now we can subtract the fractions:

\dfrac{204}{17} - \dfrac{8}{17} = \dfrac{204-8}{17} = \dfrac{196}{17}

Now we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 4 in this case:

\dfrac{196}{17} = \dfrac{196 \div 4}{17 \div 4} = \dfrac{49}{4}

So, the answer is 11 \dfrac{9}{17}.

Finally,

24 - \dfrac{5}{18} = 23 \dfrac{3}{18}

To subtract fractions, we need to have a common denominator. In this case, the common denominator is 18.

So, we need to convert the whole number 24 into a fraction with a denominator of 18:

24 = \dfrac{24}{1} \times \dfrac{18}{18} = \dfrac{432}{18}

Now we can subtract the fractions:

\dfrac{432}{18} - \dfrac{5}{18} = \dfrac{432-5}{18} = \dfrac{427}{18}

Now we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 1 in this case:

\dfrac{427}{18} = \dfrac{427 \div 1}{18 \div 1} = \dfrac{427}{18}

So, the answer is 23 \dfrac{3}{18}.

156 - \dfrac{27}{37} = 155 \dfrac{10}{37}

To subtract fractions, we need to have a common denominator. In this case, the common denominator is 37.

So, we need to convert the whole number 156 into a fraction with a denominator of 37:

156 = \dfrac{156}{1} \times \dfrac{37}{37} = \dfrac{5772}{37}

Now we can subtract the fractions:

\dfrac{5772}{37} - \dfrac{27}{37} = \dfrac{5772-27}{37} = \dfrac{5745}{37}

Now we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 1 in this case:

\dfrac{5745}{37} = \dfrac{5745 \div 1}{37 \div 1} = \dfrac{5745}{37}

So, the answer is 155 \dfrac{10}{37}.
