Ответ:
a 7/20. B 13/20
Step-by-step explanation:
800 X 35% = 280
280/800=7/20
Ответ:
a. 280/800 (or 7/20 simplified)
b. 520/800 (or 13/20 simplified)
Step-by-step explanation:
a. 800 × 0.35 = 280
Fraction of girls = total girls/total enrollment = 280/800 (or 7/20 simplified)
b. Total boys = Total enrollment - total girls = 800 - 280 = 520
Fraction of boys = total boys/total enrollment = 520/800 (or 13/20 simplified)
