either use a calculator or convert into improper fractions
7 1/2=15/2
1 1/8=9/8
so now do 15/2 divided by 9/8
turn 9/8 into reciprocal
its gonna be 8/9
then multiply
15/2 times 8/9
15*8=120
2*9=18
120/18 is your answer but simplify it or else teachers will be annoying
simplify it by 6 cause its the gcf (greatest common factor)
120/6=20
18/6=3
20/3 is ur answer as improper fraction
6 2/3 is ur answer as whole number
6.6 repeating is ur decimal
hope this helps
