Answer 2

If we subtract $\dfrac{3}{5}$ from $\dfrac{7}{20}$, we get $(-\dfrac{1}{4})$.

Step-by-step explanation:

Now, $\dfrac{7}{20}-\dfrac{3}{5}$

• We multiply the denominator of $\dfrac{3}{5}$ by $4$ to match the denominator of the first term.

• We do the same with the numerator to find the equivalent fraction.

$=\dfrac{7}{20}-\dfrac{3\times 4}{5\times 4}$

$=\dfrac{7}{20}-\dfrac{12}{20}$

• Since the LCM of $20$ and $20$ is $20$, we simply subtract the numerators.

$=\dfrac{7-12}{20}$

$=\dfrac{-5}{20}$

$=-\dfrac{1}{4}$
