If x = 1/4 and Y = 3/7
Evaluate the following expression: 7x - 4y
[tex] \\ [/tex]
[tex] \rm{7 ( \frac{1}{4}) - 4( \frac{3}{7} ) } \\ [/tex]
- Substitute the given value of x and y
[tex] \rm { \orange{7 \times \frac{1}{4} }} - 4 \times \frac{3}{7} \\ [/tex]
- Calculate the product of the rational numbers
[tex] \rm{ \frac{7}{4} - \orange{ 4 \times \frac{3}{7 }} } \\ [/tex]
- Calculate the product of the rational numbers
[tex] \rm \orange{ \frac{7}{4} - \frac{12}{7} } \\ [/tex]
- Find the difference between the two fractions
[tex] = \small{\boxed{{\sf{ \frac{1}{28} }}}}[/tex]
Therefore, the answer is 1/28.
