x=3.5
This is how I did it I took the bottom 2, 3 and 2.4 and I divided 3 by 2.4 (3/2.4) and got 1.25. I then multiplied 2.8 by 1.25 and found that x was 3.5
Answer is C. 3.5
All you need to know is that a km is 1000 m ( as the prefix kilo always means 1000 let it be even 1kg and that is equal to 1000g )
also know
that a 100 cm is 1 m and that's cause the prefix centi is 10^–2 (0.01)
answering your question
a) 5km = 5000m
5km and 20m in m is 5000m + 20m = 5020m
b) 13 cm = 13/100m = 0.13m
7m and 12cm is 7m + 0.13m = 7.13m.
remember
1km = 1000m
100cm = 1m
