Question

Принести дробь к знаменателю: (9) 14/18= 5= 2/3= 17/51= 12/27=

Answer 1

14/18=7/9(делим на 2 и числитель и знаменатель)

5=5/1=45/9(домнажаем На 9)

2/3=6/9(домнржаем на 3)

17/51=1/3=3/9делим на 17. А затем умножаем на 3)

12/27=4/3(делим на 3)

Answer 2

To bring each fraction to a common denominator, you need to find the least common multiple (LCM) of all the denominators. Then, you can rewrite each fraction using this common denominator. Let's go through each step:

Step 1: Find the least common multiple (LCM) of the denominators, which are 14, 18, 3, 51, and 27.

Prime factorization of each denominator:

• 14 = 2 * 7
• 18 = 2 * 3 * 3
• 3 = 3
• 51 = 3 * 17
• 27 = 3 * 3 * 3

LCM = 2 * 3 * 3 * 7 * 17 = 714

Step 2: Rewrite each fraction with the common denominator of 714:

a) 14/18: To get a common denominator of 714, we need to multiply both the numerator and denominator of 14/18 by 39. (14/18) * (39/39) = 546/714

b) 5: To convert 5 to a fraction with a denominator of 714, we write it as 5/1 and multiply both the numerator and denominator by 714. (5/1) * (714/714) = 3570/714

c) 2/3: To get a common denominator of 714, we need to multiply both the numerator and denominator of 2/3 by 238. (2/3) * (238/238) = 476/714

d) 17/51: To get a common denominator of 714, we need to multiply both the numerator and denominator of 17/51 by 14. (17/51) * (14/14) = 238/714

e) 12/27: To get a common denominator of 714, we need to multiply both the numerator and denominator of 12/27 by 26. (12/27) * (26/26) = 312/714

Now, all the fractions have a common denominator of 714:

• 14/18 = 546/714
• 5 = 3570/714
• 2/3 = 476/714
• 17/51 = 238/714
• 12/27 = 312/714
