how do you write 3/4 - 1/28 as a fraction
To write 3/4 - 1/28 as a fraction, we need to find a common denominator and then subtract the fractions.
The common denominator between 4 and 28 is 28, so we can rewrite the fractions with this denominator:
3/4 = (3*7)/(4*7) = 21/28
1/28 = (1*1)/(28*1) = 1/28
Now we can subtract the fractions:
21/28 - 1/28 = (21-1)/28 = 20/28
So, 3/4 - 1/28 can be written as the fraction 20/28.
thats not correct..
Apologies for the mistake. Let's reevaluate the calculation:
To subtract fractions, we need to have a common denominator. The least common multiple of 4 and 28 is 28.
Let's rewrite the fractions using the common denominator:
3/4 = (3*7)/(4*7) = 21/28
1/28 = 1/28
Now that we have a common denominator, we can subtract:
21/28 - 1/28 = (21 - 1)/28 = 20/28
However, we can simplify the fraction by dividing the numerator and denominator by their greatest common divisor, which is 4:
20/28 = (20/4)/(28/4) = 5/7
Therefore, the correct answer is 5/7.
how about: how do you write 7/8+1/12 as a fraction
To write 7/8 + 1/12 as a fraction, we need to find a common denominator and then add the fractions.
The least common multiple of 8 and 12 is 24.
Let's rewrite the fractions using the common denominator:
7/8 = (7*3)/(8*3) = 21/24
1/12
Now that we have a common denominator, we can add the fractions:
21/24 + 1/12 = (21 + 2)/24 = 23/24
So, 7/8 + 1/12 can be written as the fraction 23/24.
how do you write 2 1/2+4/16 in simplest form
(answer MUST be a mixed number)
To write 2 1/2 + 4/16 in simplest form as a mixed number, we need to first convert the mixed number to an improper fraction, then simplify if possible.
To convert the mixed number 2 1/2 to an improper fraction, we multiply the whole number (2) by the denominator (2) and add the numerator (1). This gives us:
2 1/2 = (2 * 2 + 1)/2 = 5/2
Now, let's add the fractions:
5/2 + 4/16
Since the denominators are different, we need to find a common denominator. The least common multiple of 2 and 16 is 16.
Now, let's rewrite the fractions using the common denominator:
5/2 = (5 * 8)/(2 * 8) = 40/16
4/16
Now, we can add the fractions:
40/16 + 4/16 = (40 + 4)/16 = 44/16
To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 4:
44/16 = (44/4)/(16/4) = 11/4
Therefore, 2 1/2 + 4/16 in simplest form as a mixed number is 2 3/4.
not correct
Apologies for the mistake. Let's correct the calculation:
To add a mixed number and a fraction, we need to convert the mixed number to an improper fraction, find a common denominator, and then add the fractions.
Let's start by converting the mixed number 2 1/2 to an improper fraction:
2 1/2 = (2 * 2 + 1)/2 = 5/2
Now let's find a common denominator for 5/2 and 4/16. The least common multiple of 2 and 16 is 16, so we can rewrite the fractions with this denominator:
5/2 = (5 * 8)/(2 * 8) = 40/16
4/16 = 4/16
Now we can add the fractions:
40/16 + 4/16 = (40 + 4)/16 = 44/16
To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 4:
44/16 = (44/4)/(16/4) = 11/4
Therefore, 2 1/2 + 4/16 in simplest form as a mixed number is 2 3/4.
