what is 3/5 - 1/3
To subtract fractions, you need a common denominator. In this case, we need to find a common denominator for 5 and 3, which is 15.
Rewriting the fractions with the common denominator:
(3/5) - (1/3) can be written as:
(9/15) - (5/15)
Now, subtract the numerators and keep the common denominator:
9/15 - 5/15 = (9-5)/15 = 4/15
So, 3/5 - 1/3 is equal to 4/15.
how about 5/9-3/11
To subtract fractions, we need to find a common denominator. The least common multiple (LCM) of 9 and 11 is 99.
Rewriting the fractions with the common denominator:
(5/9) - (3/11) can be written as:
(55/99) - (27/99)
Now, we can subtract the numerators while keeping the common denominator:
55/99 - 27/99 = (55 - 27)/99 = 28/99
So, 5/9 - 3/11 is equal to 28/99.
what about 1/2+2/9
To add fractions, you need a common denominator. In this case, the least common multiple (LCM) of 2 and 9 is 18.
Rewriting the fractions with the common denominator:
(1/2) + (2/9) can be written as:
(9/18) + (4/18)
Now, add the numerators while keeping the common denominator:
9/18 + 4/18 = (9 + 4)/18 = 13/18
So, 1/2 + 2/9 is equal to 13/18.
what about 7/20+7/12
To add fractions, you need a common denominator. In this case, the least common multiple (LCM) of 20 and 12 is 60.
Rewriting the fractions with the common denominator:
(7/20) + (7/12) can be written as:
(21/60) + (35/60)
Now, add the numerators while keeping the common denominator:
21/60 + 35/60 = (21 + 35)/60 = 56/60
Since 56 and 60 can both be divided by 4, we can simplify the fraction:
56/60 = (56 ÷ 4) / (60 ÷ 4) = 14/15
So, 7/20 + 7/12 is equal to 14/15.
what about 7/12-5/9
To subtract fractions, you need a common denominator. In this case, the least common multiple (LCM) of 12 and 9 is 36.
Rewriting the fractions with the common denominator:
(7/12) - (5/9) can be written as:
(21/36) - (20/36)
Now, subtract the numerators while keeping the common denominator:
21/36 - 20/36 = (21 - 20)/36 = 1/36
So, 7/12 - 5/9 is equal to 1/36.
