#color(blue)"mixed numbers into improper fractions"#
#rArr6 1/2=6+1/2=12/2+1/2=13/2# and
#1 1/8=1+1/8=8/8+1/8=9/8#
#rArr6 1/2÷1 1/8=13/2÷9/8# To divide 2 fractions : change ÷ to × and invert (turn) the 2nd fraction.
#rArr13/2÷9/8=13/2xx8/9# now that we have multiplication we can cancel out any common factors between the numerators and denominators.
#rArr13/(cancel(2)^1)xx(cancel(8)^4)/9=(13xx4)/(1xx9)=52/9=5 7/9#
