Answer:
12/56
Step-by-step explanation:
The additive inverse of a number N is -N. Thus a number added to its additive inverse will be 0N + (-N) = 0Step 1:
Find the result of [tex]-\frac{3}{8} - (-\frac{2}{7} )[/tex][tex]-\frac{21}{56} - (-\frac{16}{56} )[/tex]
= [tex]-\frac{21}{56} - (-\frac{16}{56} )[/tex] making denominator equal and adjusting numerator
= [tex]-\frac{21}{56} + \frac{16}{56}[/tex]
= [tex]\frac{-21 + 16}{56}[/tex] = [tex]-\frac{5}{56}[/tex] (1)Step 2:
Find the inverse of [tex]-\frac{5}{56}[/tex]. This is [tex]\frac{5}{56}[/tex] (2)
Step 3
Find the sum of [tex]\frac{1}{4} and -\frac{3}{8}[/tex][tex]\frac{1}{4} + (-\frac{3}{8})[/tex] = [tex]\frac{1}{4} - \frac{3}{8}[/tex] = [tex]\frac{2}{8} - \frac{3}{8}[/tex] = [tex]\frac{1}{8}[/tex] (3)
Step 4
(2) - (3) ==> [tex]\frac{5}{56} - (-\frac{1}{8}) \\= \frac{5}{56} + \frac{1}{8} \\\\= \frac{5}{56} + \frac{7}{56}) \\\\= \frac{12}{56} or \frac{3}{14}[/tex]

Step-by-step explanation:
The additive inverse of a number N is -N. Thus a number added to its additive inverse will be 0
N + (-N) = 0
Step 1:
Find the result of
[tex]-\frac{3}{8} - (-\frac{2}{7} )[/tex][tex]-\frac{21}{56} - (-\frac{16}{56} )[/tex]
= [tex]-\frac{21}{56} - (-\frac{16}{56} )[/tex] making denominator equal and adjusting numerator
= [tex]-\frac{21}{56} + \frac{16}{56}[/tex]
= [tex]\frac{-21 + 16}{56}[/tex] = [tex]-\frac{5}{56}[/tex] (1)
Step 2:
Find the inverse of [tex]-\frac{5}{56}[/tex]. This is [tex]\frac{5}{56}[/tex] (2)
Step 3
Find the sum of [tex]\frac{1}{4} and -\frac{3}{8}[/tex]
[tex]\frac{1}{4} + (-\frac{3}{8})[/tex] = [tex]\frac{1}{4} - \frac{3}{8}[/tex] = [tex]\frac{2}{8} - \frac{3}{8}[/tex] = [tex]\frac{1}{8}[/tex] (3)
Step 4
(2) - (3) ==> [tex]\frac{5}{56} - (-\frac{1}{8}) \\= \frac{5}{56} + \frac{1}{8} \\\\= \frac{5}{56} + \frac{7}{56}) \\\\= \frac{12}{56} or \frac{3}{14}[/tex]
