Question

estimate is some to the nearest ten also find the difference between the estimate sum and the actual sum 809+405​

Answer 1

Answer:

Step-by-step explanation:

real solution: 809 + 405 =1214

esti8mated amounts:

809 = 810(nearest 10)

405 = 410(nearest 10)

therefore ;

estimated solution = 810 + 410 = 1220

difference between, estimated sum and real sum = 1220 - 1214 = 6
