Question

What should be subtracted from -4/7 to get -3/5 ? *​

Answer 1

Answer:

let the number subtracted be x

-4/7 - x = -3/5

-×= -3/5+4/7

-x= lcm =35

-x= -21/35+20/35

-×= -41/35

×=41/35

Answer 2

Step-by-step explanation:

$\frac{ - 4}{7} - \frac{ - 3}{5 } \\ \\ \frac{ - 20 - - 21}{35 } \\ \frac{ - 20 + 21}{35 } \\ \frac{1}{35}$

1-first multiply 7×5=35

2-multiply5×(-4)=-20

3-multiply7×(-3)=-21

then (-20)-(-21)/35

(-×-=+)

-20+21=1
