Посадили 56 деревьев, 7/8 посаженных деревьев прижились. Сколько деревьев прижилось? Турист должен пройти 27 км. Он прошёл 2/3 всего пути. Сколько километров ему осталось пройти?

Answer 1

Пошаговое объяснение:

а) 15/50=3/10

б) 42/49=6/7

в) 12/24=1/2

г) 9/27=1/3

а)

3/5 и 2/5

3 > 2

3/5 > 2/5

б)

2/8 и 4/8

2 < 4

2/8 < 4/8

в)

23/24 и 1

23/24 и 24/24

23 < 24

23/24 < 1

56 деревьев — 1 ч

Х деревьев — 7/8 ч

Х=56×7/8:1=49 деревьев прижились

27 км — 1 ч

Х км —2/3 ч

Х=27×2/3:1=18 км прошел

27-18=9 км осталось пройти

Answer 2

Simplifying Fractions:

a) To simplify the fraction 15/50, we can divide both the numerator and denominator by their greatest common divisor (GCD), which is 5. Dividing 15 by 5 gives us 3, and dividing 50 by 5 gives us 10. Therefore, the simplified form of 15/50 is 3/10.

b) For the fraction 42/49, we can simplify it by dividing both the numerator and denominator by their GCD, which is 7. Dividing 42 by 7 gives us 6, and dividing 49 by 7 gives us 7. So, the simplified form of 42/49 is 6/7.

c) The fraction 12/24 can be simplified by dividing both the numerator and denominator by their GCD, which is 12. Dividing 12 by 12 gives us 1, and dividing 24 by 12 gives us 2. Hence, the simplified form of 12/24 is 1/2.

d) To simplify the fraction 9/27, we can divide both the numerator and denominator by their GCD, which is 9. Dividing 9 by 9 gives us 1, and dividing 27 by 9 gives us 3. Therefore, the simplified form of 9/27 is 1/3.
