a) (42)/(56)= do (24)/(36)=

To simplify the fractions, we need to find the greatest common divisor (GCD) of the numerator and denominator and divide both by it.<br /><br />For $\frac{42}{56}$:<br />The GCD of 42 and 56 is 14.<br />Dividing both the numerator and denominator by 14, we get:<br />$\frac{42}{56} = \frac{42 \div 14}{56 \div 14} = \frac{3}{4}$<br /><br />For $\frac{24}{36}$:<br />The GCD of 24 and 36 is 12.<br />Dividing both the numerator and denominator by 12, we get:<br />$\frac{24}{36} = \frac{24 \div 12}{36 \div 12} = \frac{2}{3}$<br /><br />Therefore, the simplified fractions are:<br />$\frac{42}{56} = \frac{3}{4}$<br />$\frac{24}{36} = \frac{2}{3}$
