Estimate.Then find the product 1,925 ×7<br><br>Please show work
Licemer1 [7]

1,925 is close to 2,000

so 2,000 x 7 = 14,000

1,925 x 7 = ?

5 x 7 = 35

20 x 7 = 140

900 x 7 = 6,300

1,000 x 7 = 7,000

so 7,000 + 6,300 + 140 + 35 = 13,475 and 13,475 is close to 14,000 or 13,500 or 13,470.

Hope this helps even though a little confusing! ;D
