Question

which expression is the best estimate of 1.25+(-2.69)

Answer 1

This would equal -1.44. Hope this helps!

Answer 2

A. 1+(-3)

To find it, you'd have to round both decimals. 1.25 rounds to 1, while -2.69 rounds to 3. That would make a similar expression 1 + (-3) and that's your first answer.
