Explain how you would subtract -4/5 from 9/10 .

-17/10

Step-by-step explanation:

you have to find a common denomentaor first wich would be 10

then you have to mutiply -4/5 by 2 which would be -8/10

and then you would do regular subtraction

but since its a negative number your gonna actually add but then the final answer will be negative

-17/10

hope this helps I really suck with fractions

it would be 6xy and -16xy.
