here is your answers example

Step-by-step explanation:

 (a) We have, 578 x 161 578 → 600                 [rounding off to nearest hundreds] 161 → 200 [rounding off to nearest hundreds] ∴ Estimated product = 600 x 200 = 1,20,000 (b) We have, 5281 x 3491 5281 → 5000             [rounding off to nearest thousands] 3491 → 3500                             [rounding off to nearest hundreds] ∴ Estimated product = 5000 x 3500 = 1,75,00,000 (c) We have, 1291 x 592 1291→ 1300              [rounding off to nearest hundreds] 592→ 600                  [rounding off to nearest hundreds] ∴ Estimated product = 1300 x 600 = 7,80,000 (d) We have, 9250 x 29 9250→9000               [rounding off to nearest thousands] 29 →30              [rounding off to nearest tens] ∴ Estimated product = 9000 x 30 = 2,70,000
