please answer correctly ​

Answer 1

Answer:

We  will get the value $\frac{-2}{5} -(\frac{-7}{20}) =-\frac{1}{20} .$

Step-by-step explanation:

• We have to evaluate the above expression by using the given data.

        Given data:- $\frac{-2}{5} -(\frac{-7}{20}) .$

        To find:- Value of the given expression.

        Solution:-

• We will take the LCM of the denominators, and make denominators the same.

• We will Convert the given fractions to equivalent fractions with the denominator as the LCM.

• Subtract the numerators over the denominators.

        Therefore,

         $\frac{-2}{5} -(\frac{-7}{20}) \\\\=\frac{-2}{5}-\frac{-7}{20} \\\\=\frac{-2 \times 4}{5 \times 4}-\frac{-7}{20} \\\\=\frac{-8}{20}-\frac{-7}{20} \\\\=\frac{-8--7}{20} \\\\=-\frac{1}{20}\end{array}$
