Complete this conversion. given: 10 mm = 1 cm given: 100 cm = 1 m find: 7.5 m = ___ mm
krek1111 [17]
We have that
10 mm is equal to -------> 1 cm----> multiply by 100
10*100 mm is equal to -------> 1*100 cm
1000 mm is equal to -------> 100 cm
and
we know that
100 cm is equal to-------> 1 m
therefore
1000 mm is equal to -------> 100 cm
100 cm is equal to-------> 1 m

1000 mm is equal to--------> 1 m
  X mm-----------------> 7.5 m
x-7.5*1000-----> x=7500 mm

the answer is
7500 mm
