Answer: -25 / 36
Solution:
Step 1: Lets flip the division sign to multiplication
Note : when the sign is reversed, the second term in the equation will have the numerator and denominator swapped
-5/8 ÷9/10 > > > > > > -5/8 * 10/9
Step 2 : so it will be
-5/4 * 5/9 when simplified, which would be -25 / 36 > > > > > - 0.69
Hope this solution will help you understand the problem and don't forget the negative sign it may cost you marks :)
