The ceiling in Clara basement is 2.75 meter high. When Clara jumps she is 18 centimeters short of being able to touch the ceiling. How high can Clara reach when she jumps?

257 cm or 2.57 Meters

Step-by-step explanation:

Height of ceiling = 2.75 meters

Height of ceiling in centimetre = 2.75*100 = 275 cm (as 1 m = 100 cm)

It is given that when Clara jumped she was short of 18 cm to touch the ceiling.

So, it can be concluded that difference of ceiling's height and Clara's jump is 18 cm

Difference of height of ceiling and Clara's jump = 18 cm

Height of ceiling - height of Clara's jump = 18 cm

275 - height of Clara's jump = 18 cm

=>height of Clara's jump = 275 - 18 = 257 cm.

Thus, Clara can jump 257 cm high.

In meters, she can jump 257/100 = 2.57 Meters (As 1 m = 100 cm).
