Simplify 10 1/2 - 2 3/4?

Answer 1

10.5 - 2.75 = 7.75 :)

Answer 2

= 2 3/4

Answer 3

To solve this, you need to change the mixed numbers into fractions.

To do this, multiply the denominator and the whole number and add the numerator. Then put that number over the current denominator.

10 1/2
2(10) + 1 =21
10 1/2 = 21/2

2 3/4
4(2) + 3 = 11
2 3/4 = 11/4

Now your problem is:
21/2 - 11/4

You need to have like denominators. You can use 4 because 2 and 4 both go into it evenly.

21/2 = ?/4

2(2) = 4
21(2) = 42

21/2 = 42/4

Now you have:
42/4 - 11/4

Simply subtract the numerators, keep the denominator.
42 - 11 = 31

42/4 - 11/4 = 31/4

There is your answer.

Answer 4

7 3/4

Answer 5

This is somewhat an easy problem.

I think you know how to calculate the mixed calculations.
First, 10 1/2 = 21/2
Then. 2 3/4 = 11/4

For easier calculation, 21/2 can bewritten as 42/4. Or else you can take the LCM and then proceed.
But I am choosing the first way.
42/4 - 11 /4
= 31/4

31/4 can be written as 7 3/4 or 7.75.

So the required answer is 7 3/4 or 7.75.

Hope this is easier to understand.

Answer 6

7 3/4

Answer 7

10 1/2 -2 3/4
= 21/2 - 11/4
= 42/4 - 11/4
= 31/4

Answer 8

You have 3 different answers so far. Lets see where mine fits in.

10 1/2 - 2 3/4

One approach is to first change the mixed numbers to improper fractions

21/2 - 11/4

In order to combine these fractions, change the left fraction to 4ths by multiplying both the numerator and the denominator by 2

42/4 - 11/4

31/4

7 3/4

Answer 9

11/2 - 11/4
=22/4 - 11/4
=11/4
=2 3/4

Answer 10

10 1/2 - 2 3/4

render these improper fractions, so they read

21/2 - 11/4

find lowest common denominator, so this problem reads

42/4 - 11/4

subtract 11 from 42, so the answer reads

31/4

which as a mixed number is rendered

7 3/4

Answer 11

10 1/2 - 2 3/4
21/2 - 11/4
42/4 - 11/4
31/4

7 3/4
