First of all, a meter is equal to 100cm.
[tex]1m=100cm[/tex]
Seb made a jump of two and a half meters. ([tex]2 \frac{1}{2} [/tex] or [tex]2.5[/tex])
Multiply 100 by 2.
[tex]100*2=200[/tex]
Now we need the half.
What is half of 100?
50 is half of 100.
So, add 50 to the 200.
[tex]200+50=250[/tex]
Kirsty's jump was 10 centimeters longer.
Add 10 centimeters to the 250 centimeters.
[tex]250+10=260[/tex]
Kirsty's jump was 260 centimeters high, or 2.55 meters.
