Pls help I have quiz on tuesday and I don't get this stuff...
How do I subtract...
1. 8/d - 3/d
2. 1 - 8/9
1 - (8/9) = (9/9)-(8/9) = 1/9
(8/d) - (3/d) = ??
1. Since the denominators are the same, just subtract the numerators.
8/d - 3/d = 5/d
2. Change the whole number to a fraction.
1 - 8/9
9/9 - 8/9 = ?
so it will be 1 over 1 minus 8 over then I multiply them?
Sure, I can help you with that!
To subtract fractions, you follow these steps:
1. Make sure both fractions have the same denominator. If they don't, find a common denominator by multiplying the denominators together. For example, if you have 8/d and 3/d, the common denominator is d.
Therefore, 8/d - 3/d can be written as (8 - 3)/d.
2. Simplify the numerator. In this case, subtract 8 - 3 to get 5. So the numerator becomes 5/d.
3. Keep the denominator the same. Since both fractions have a denominator of d, it remains as d.
Therefore, the result of 8/d - 3/d is 5/d.
For the second question, 1 - 8/9, follow these steps:
1. Convert the whole number 1 into a fraction with the same denominator as the fraction 8/9. In this case, we can write 1 as 9/9.
2. Write the expression as a fraction with a common denominator. This gives us (9/9 - 8/9).
3. Subtract the numerators. In this case, subtract 9 - 8 to get 1. So the numerator becomes 1/9.
4. Keep the denominator the same, which is 9.
Therefore, the result of 1 - 8/9 is 1/9.
Remember to always simplify the fraction if possible.
