Question

Сведите к наименьшоему общему знаменателю дроби 5/12 и 1/8; 7/8 и 15/16; 2/15 и 5/12 пж пж !!!

Answer 1

5/12 и 1/8 и 15/16 = 20/48 и 6/48 и 45/48
2/15 и 5/12 = 8/60 и 25/60

Answer 2

5/12=5*2/12*2=10/24             1/8=1*3/8*3=3/24
7/8=7*2/8*2=14/16          15/16
2/15=2*4/15*4=8/60                5/12=5*5/12*5=25/60

Answer 3

Simplifying Fractions

To find the least common denominator (LCD) and simplify fractions, we need to find the smallest number that both denominators can divide evenly into. Let's simplify the given fractions:

1. 5/12 and 1/8: - The LCD of 12 and 8 is 24. - To convert 5/12 to have a denominator of 24, we multiply both the numerator and denominator by 2: (5/12) * (2/2) = 10/24. - To convert 1/8 to have a denominator of 24, we multiply both the numerator and denominator by 3: (1/8) * (3/3) = 3/24. - Therefore, the simplified fractions are 10/24 and 3/24.

2. 7/8 and 15/16: - The LCD of 8 and 16 is 16. - To convert 7/8 to have a denominator of 16, we multiply both the numerator and denominator by 2: (7/8) * (2/2) = 14/16. - The fraction 15/16 already has the same denominator. - Therefore, the simplified fractions are 14/16 and 15/16.

3. 2/15 and 5/12: - The LCD of 15 and 12 is 60. - To convert 2/15 to have a denominator of 60, we multiply both the numerator and denominator by 4: (2/15) * (4/4) = 8/60. - To convert 5/12 to have a denominator of 60, we multiply both the numerator and denominator by 5: (5/12) * (5/5) = 25/60. - Therefore, the simplified fractions are 8/60 and 25/60.

So, the simplified fractions are: - 5/12 and 1/8 become 10/24 and 3/24. - 7/8 and 15/16 remain as 14/16 and 15/16. - 2/15 and 5/12 become 8/60 and 25/60.
