Question

If a = {(2/5) - (1/4)] , then find the value of a and also, find the difference between the additive inverse and
multiplicative inverse of a.

Answer 1

Answer:

a= $\frac{3}{20}$

the difference is $-\frac{409}{60}$

Step-by-step explanation:

1) Calculate a:$\frac{2}{5} -\frac{1}{4} = \frac{8}{20} -\frac{5}{20} = \frac{3}{20}$

2) additive inverse is $-\frac{3}{20}$, multiplication inverse is $\frac{20}{3}$

So to calculate the difference:

$-\frac{3}{20}-\frac{20}{3} = -\frac{9}{60} - \frac{400}{60} = -\frac{409}{60}$
