Answer:

see below

Step-by-step explanation:

2 1/2+ 3 3/16 + 7/8

Get a common denominator of 16

2 8/16 + 3 3/16 + 14/16

5 25/16

5 + 16/16 + 9/16

6 9/16

Subtract this from 8 ft

8 - 6 9/16

Borrow 1 from 8 in the form of 16/16

7 16/16 - 6 9/16

1 7/16

b  1 7/16 - 1 1/3

The common denominator is 48

1 21/48    - 1 16/48

5/48

Answer:

2a)   [tex]1\frac{7}{16}[/tex]

2b)   [tex]\frac{5}{48}[/tex]

Step-by-step explanation:

The first thing we need to do is add all the fractions together so,

2a)      [tex]2\frac{1}{2} +3\frac{3}{16}+\frac{7}{8}[/tex]

We need to find the LCM of the denominators in order to properly add the fractions together so the LCM is 16

[tex]2\frac{1}{2} +3\frac{3}{16}+\frac{7}{8}[/tex]   =  [tex]2\frac{8}{16} +3\frac{3}{16} +\frac{14}{16} = 5\frac{25}{16} =6\frac{9}{16}[/tex]

Now we subtract this from 8 as asked in the question,

[tex]8-6\frac{9}{16} =\frac{8}{1} -\frac{105}{16} =\frac{128}{16} -\frac{105}{16}=\frac{23}{16} =1\frac{7}{16}[/tex]

2b) We are asked to minus the fraction   [tex]1\frac{7}{16}[/tex]   from    [tex]1\frac{1}{3}[/tex]

Find the common denominator which is 48

[tex]1\frac{7}{16} -1\frac{1}{3} =1\frac{21}{48} -1\frac{16}{48} =\frac{5}{48}[/tex]
