Estimate 219 and 445

Mathematics
1 answer:
Rama09 [41]4 years ago

Estimation: 200 and 400. If a number is less than 50, depending on whether in the hundreds or thousands (1500 in this case), the number can be estimated to 2000. But since both numbers are less than 250 or 450, the number remains 200 and 400
