Ответ:
The area of the polo field is 300 yd x 160 yd = 48000 yards
The football field is 160 feet wide. THere are 3 feet per yard, so
the football field is 160/3 = 53 and 1/3 yards wide.
So the area of the football field is 100 yards x 53 1/3 yards
= 100 yards x 160/3 yd
= 16000/3 square yards
= 5333 and 1/3 square yards
Dividing these areas, then they will need 48000 / (5333 and 1/3)
48000 / (16000/3) =
48000 * 3 / 16000 <-- dividing fractions; KFC: keep, flip, change; (reciprocal)
3 * 3 < 48000 cancels 16000 3 times
