Step-by-step explanation:
What is 7/8 - 3/4?
What is 7/8 - 3/4?
Here's how to subtract 3/4 from 7/8:
7
8
−
3
4
Step 1
We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.
So we multiply 7 by 4, and get 28.
Then we multiply 3 by 8, and get 24.
Next we give both terms new denominators -- 8 × 4 = 32.
So now our fractions look like this:
28
32
−
24
32
Step 2
Since our denominators match, we can subtract the numerators.
28 − 24 = 4
So the answer is:
4
32
Step 3
Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?
To find out, we try dividing it by 2...
Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
4 32 ÷ 2 = 2 16
Let's try dividing by 2 again...
Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
2 16 ÷ 2 = 1 8
Let's try dividing by 2 again...
No good. 2 is larger than 1. So we're done reducing.
There you have it! The final answer is:
7 8 − 3 4 = 1 8
