Summary of Expressions Equivalent to ( \frac{1}{4} + \frac{7}{8} )

Part A: Equivalent Expressions
To determine which expressions are equivalent to ( \frac{1}{4} + \frac{7}{8} ), we can analyze the options provided:

  • Option 1: ( \frac{2}{8} + \frac{7}{8} )
    This simplifies to ( \frac{9}{8} ), which is not equivalent to ( \frac{1}{4} + \frac{7}{8} ).

  • Option 2: ( \frac{4}{16} + \frac{15}{16} )
    This simplifies to ( \frac{19}{16} ), which is also not equivalent to ( \frac{1}{4} + \frac{7}{8} ).

  • Option 3: ( \frac{8}{24} + \frac{21}{24} )
    This simplifies to ( \frac{29}{24} ), which is not equivalent.

  • Option 4: ( \frac{7}{32} + \frac{28}{32} )
    This simplifies to ( \frac{35}{32} ), which does not match either.

  • Option 5: ( \frac{10}{40} + \frac{35}{40} )
    This simplifies to ( \frac{45}{40} ), which is not equal to ( \frac{1}{4} + \frac{7}{8} ).

In conclusion, none of the provided options (2/8+7/8, 4/16+15/16, 8/24+21/24, 7/32+28/32, 10/40+35/40) are equivalent to ( \frac{1}{4} + \frac{7}{8} ).

Part B: Calculation of ( \frac{1}{4} + \frac{7}{8} )
Now, calculating ( \frac{1}{4} + \frac{7}{8} ):

  1. The common denominator for these fractions is 8.
  2. Rewrite ( \frac{1}{4} ) as ( \frac{2}{8} ).
  3. Now add:
    [ \frac{2}{8} + \frac{7}{8} = \frac{9}{8} \text{ or } 1 \frac{1}{8} ]

Given the calculation, the only correct answer is ( 1 \frac{1}{8} ).

This summary provides both the analysis of expression equivalences and the calculation result for the given fractions.In Part A of the problem, you are asked to select all expressions that are equivalent to ( \frac{1}{4} + \frac{7}{8} ). The expressions provided for evaluation are:

  1. ( \frac{2}{8} + \frac{7}{8} )
  2. ( \frac{4}{16} + \frac{15}{16} )
  3. ( \frac{8}{24} + \frac{21}{24} )
  4. ( \frac{7}{32} + \frac{28}{32} )
  5. ( \frac{10}{40} + \frac{35}{40} )

To determine which of these equations is equivalent to ( \frac{1}{4} + \frac{7}{8} ), we first need to find a common denominator in the original equation. The common denominator for ( \frac{1}{4} ) and ( \frac{7}{8} ) is 8. Therefore, ( \frac{1}{4} ) can be converted to ( \frac{2}{8} ). Thus:

[ \frac{1}{4} + \frac{7}{8} = \frac{2}{8} + \frac{7}{8} = \frac{9}{8} ]

Next, we can evaluate each of the provided expressions:

  1. ( \frac{2}{8} + \frac{7}{8} = \frac{9}{8} ) (equivalent)
  2. ( \frac{4}{16} + \frac{15}{16} = \frac{19}{16} ) (not equivalent)
  3. ( \frac{8}{24} + \frac{21}{24} = \frac{29}{24} ) (not equivalent)
  4. ( \frac{7}{32} + \frac{28}{32} = \frac{35}{32} ) (not equivalent)
  5. ( \frac{10}{40} + \frac{35}{40} = \frac{45}{40} = \frac{9}{8} ) (equivalent)

Thus, the expressions that are equivalent to ( \frac{1}{4} + \frac{7}{8} ) are ( \frac{2}{8} + \frac{7}{8} ) and ( \frac{10}{40} + \frac{35}{40} ).

In Part B, you are asked to calculate the expression ( \frac{1}{4} + \frac{7}{8} ). As previously calculated, we found that the sum is:

[ \frac{1}{4} + \frac{7}{8} = \frac{9}{8} ]

This can also be expressed as a mixed number:

[ \frac{9}{8} = 1 \frac{1}{8} ]

From the choices presented, the correct answer is ( 1 \frac{1}{8} ).

In summary, for Part A, the equivalent expressions are ( \frac{2}{8} + \frac{7}{8} ) and ( \frac{10}{40} + \frac{35}{40} ). For Part B, the result of ( \frac{1}{4} + \frac{7}{8} ) is ( 1 \frac{1}{8} ).
