Answer 1

`\huge\text{Hey there!}`

`\mathsf{(1)/(4) - (1)/(2) * -(4)/(7)}`

`\mathsf{= (1)/(4) - (1*-4)/(2*7)}`

`\mathsf{= (1)/(4) - (-4)/(14)}`

`\mathsf{= (1)/(4) - (-4/2)/(14/2)}`

`\mathsf{= (1)/(4) - (-2)/(7)}`

`\mathsf{= (1)/(4) + (2)/(7)}`

`\mathsf{= (15)/(28)}`

`\huge\text{Therefore, your answer should be:}`

`\huge\boxed{\mathsf{ (15)/(28)}}\huge\checkmark`
