Question

Запишите в виде несократимой дроби: а) 28/32 б) 180/315 С РЕШЕНИЕМ!!!

Answer 1

а) 28/32=7/8(сокращаем и числитель и знаменатель на 4)
 б) 180/315=12/21(сократили на 15)=4/7(сократили на 3)

Answer 2

а) 28/32:

To write the fraction 28/32 as an irreducible fraction, we need to find the greatest common divisor (GCD) of the numerator and the denominator and divide both by it. The GCD of 28 and 32 is 4. So, dividing both the numerator and the denominator by 4, we get:

28 ÷ 4 = 7 32 ÷ 4 = 8

Therefore, the irreducible fraction for 28/32 is 7/8.

b) 180/315:

To write the fraction 180/315 as an irreducible fraction, we need to find the GCD of the numerator and the denominator and divide both by it. The GCD of 180 and 315 is 45. So, dividing both the numerator and the denominator by 45, we get:

180 ÷ 45 = 4 315 ÷ 45 = 7

Therefore, the irreducible fraction for 180/315 is 4/7.

I hope this helps! Let me know if you have any further questions.
