Question

Seb made a jump of two and a half meters Kirsty's jump was 10 centimeters longer how long was Kirsty's jump

Answer 1

2m 60cm is think because half off 100 is 50 so add 10 on and you get 60

Answer 2

First of all, a meter is equal to 100cm.

`1m=100cm`

Seb made a jump of two and a half meters. (
`2 (1)/(2)` or
`2.5`)
Multiply 100 by 2.


`100*2=200`

Now we need the half.
What is half of 100?
50 is half of 100.

So, add 50 to the 200.


`200+50=250`

Kirsty's jump was 10 centimeters longer.

Add 10 centimeters to the 250 centimeters.

`250+10=260`

Kirsty's jump was 260 centimeters high, or 2.55 meters.
