Find out from the table —
Galina's long jump is nearly
(a) 7 metres
(b) 7 and a half metres
(c) 8 metres

Answer 1

Correct: (b) 7 and a half metres
Long jump of Galina C. = 7 m 52 cm
We know
1 m = 100 cm
Half metre = 50 cm
Now,
Galina C.'s long jump = 7 m + 52 cm
= (7$\times$100) cm + 52 cm
= 700 cm + 52 cm
= 752 cm
We know
7 m = 700 cm
7 and a half metres = 7 m + Half metre
= 700 cm + 50 cm
= 750 cm
8 m = 800 cm
750 cm is close to 752 cm.
Thus, Galina C.'s long jump is nearly seven and a half metres.
