How can 6.75 + (-10.25) be expressed as the sum of its integer and decimal parts?

answer:

option a = -6 + (-10)+ (-0.75) + (-0.25)

step-by-step explanation:

by considering the question in the picture:

we have to find sum and integer part of:

- 6.75 + (-10.25)

option a = -6 + (-10)+ (-0.75) + (-0.25)   is the right answer. as above equation has both signs "-", so when a positive decimal part will be added it will actually be subtracted from integers as

                  -2a + a = -a (gives subtraction)

but if the decimal part would also be negative then both the parts will be added because we know

                  -2a - a = -3a (gives addition)

i hope it will you!
