Is this your problem for 3?
5/8 - (-2/8)
That is not the problem you posted and the one that ooblek answered.
oh wait
sorry i thought i added the negative
To solve these problems, you need to perform the arithmetic operations indicated and simplify the resulting fraction, if possible.
3. 5/8 - (2/8)
First, find the common denominator, which in this case is 8. Since the denominators are already the same, you can subtract the numerators directly: 5 - 2 = 3. The answer is 3/8.
So, the correct answer is C. 3/8.
4. -9/10 - 2/5
First, find the common denominator, which in this case is 10. To convert 2/5 into a fraction with a denominator of 10, multiply both the numerator and denominator by 2: (2 × 2) / (5 × 2) = 4/10.
Now you can subtract the fractions: -9/10 - 4/10 = -13/10.
To simplify the fraction, you can reduce it by dividing both the numerator and denominator by their greatest common divisor, which is 1 in this case. The simplified fraction is -13/10.
However, the problem asks for the result as a mixed number. To convert the improper fraction -13/10 into a mixed number, divide the numerator (-13) by the denominator (10). The quotient is the whole number, and the remainder is the numerator for the fraction part: -13 ÷ 10 = -1 remainder -3.
So, the answer is A. -1 3/10.
Your answers are correct for both questions! Well done!
