what is the answer to 8 1/8-3 5/6 and how?

8 1/8= 65/8
3 5/6= 23/6

required = 65/8- 23/6

= (195- 92) /24

=103/24 = 4 7/24

Method 1
5 + (3/24 - 20/24)
4 + (27/24 - 20/24)
4 7/24

Method 2
65/8 - 23/6
195/24 - 92/24
103/24
4 7/24

Method 3
8 3/24 - 3 20/24
7 27/24 - 3 20/24
4 7/24

Which one do you prefer?

8 1/8 - 3 5/6
= 8 3/24 - 3 20/24
= (8 - 3) + (3/24 - 20/24)
= (7 - 3) + (27/24 - 20/24)
= 4 + 7/24
= 4 7/24

8 1/8= 65/8

3 5/6= 23/6


required = 65/8- 23/6

Make same denominator
= (195- 92) /24

=103/24 = 4 7/24

change mixed in to improper fraction
8 1/8 = 65/8 & 3 5/6 = 23/6

find l.c.m for 8 and 6 = 24

multiply the numerators of i no with 3 and ii no with 4
and subtract them

195 - 92 / 24 = 103 / 24 = 4 7/24

note: i answered you seriously

8 1/8= 65/8

3 5/6= 23/6

65/8- 23/6= 195- 92 /24

=103/24 = 4 7/24

4 7/24

First you chang the mixed numbers to an improper fraction. so you get:
65/8 and 23/6
Then you have to make the denominator the same:
390/48 and 184/48
Now take them away:
206/48
Then you simplyfiy them to get:
103/24 or 4 7/24

what i do is changing the two fractions to improper fraction;

65/8-23/6

then make the two fractions similar fractions.

195/24 - 414/24
and proceed to the indicated operation(which is subtraction).

-219/24. then simplify if possible.

-219/24 = -73/8

so the answer is -73/8.
Your answer could be in improper fraction or mixed fraction form, depending on what your teacher prefer.

4 2/3
