Answer:
The answer will be: [tex]\frac{17}{40}[/tex]
Step-by-step explanation:
The given expression is: [tex]\frac{3}{5}+(-\frac{1}{4}) \frac{7}{10}[/tex]
First we need to multiply [tex]-\frac{1}{4}[/tex] and [tex]\frac{7}{10}[/tex]. So, we will get.......
[tex]\frac{3}{5}+(-\frac{7}{40}) \\ \\ =\frac{3}{5}- \frac{7}{40}[/tex]
Now, we need to make both denominators equal. So.........
[tex]\frac{3\times8}{5 \times 8}-\frac{7}{40} \\ \\ =\frac{24}{40}- \frac{7}{40} \\ \\ =\frac{24-7}{40}= \frac{17}{40}[/tex]
So, the answer will be: [tex]\frac{17}{40}[/tex]
