How is 47.3 divided by 1 tenth equal to the product 47.3 times 0.1
Mice21 [21]
Misunderstood.
One tenth is 0.1. If you divide by it you multiply by 10. If you want one tenth of something, you multiply that something by one tenth, that is by 0.1.
One tenth of 47.3 is 47.3 * 0.1 = 4.73. Dividing 47.3 by one tenth you get 473.

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
