Find out from the table —
Whose high jump is very close to two and half metres?
(a) Stefka K.
(b) Chandra Pal
(c) Javier S.
(d) Bobby A.

Answer 1

We know
1 m = 100 cm
0.5 m = 50 cm
Two and half metres = 2 m + Half metre
= (2$\times$100) cm + 50 cm
= 200 cm + 50 cm
= 250 cm

High jump of Stefka K. = 2 m 9 cm
= (2$\times$100) cm + 9 cm
= 200 cm + 9 cm
= 209 cm

High jump of Chandra Pal = 2 m 17 cm
= (2$\times$100) cm + 17 cm
= 200 cm + 17 cm
= 217 cm

High jump of Javier S. = 2 m 45 cm
= (2$\times$100) cm + 45 cm
= 200 cm + 45 cm
= 245 cm

High jump of Bobby A. = 1 m 91 cm
= 100 cm + 91 cm
= 191 cm

245 cm is very close to 250 cm.

Thus, the high jump of Javier S. is very close to two and half metres.
