Answer:
[tex] \frac{13}{35} [/tex]
Step-by-step explanation:
To add or subtract two or more fractions from each other, the denominators have to be the same. To make the denominators the same, we should find the least common multiple of 5 and 7. The least common multiple of 5 and 7 is 35. 5 should be multiplied with 7 to get 35 and 7 should be multiplied with 5 to get 35 (with both numerators).
[tex] \frac{4}{5 } - \frac{3}{7} [/tex]
[tex] \frac{4 \times 7}{5 \times 7} - \frac{3 \times 5}{7 \times 5} [/tex]
[tex] \frac{28}{35} - \frac{15}{35} [/tex]
[tex] \frac{13 }{35} [/tex]
When subtracting, only subtract the numerators (the denominators are kept as is).
