38 x 2 =
The answer is 2,800. To estimate the product of 2 numbers, you round to the nearest ten or hundred. In this case, you would round 73 to 70, and 403 to 400, to make it easy to multiply. 70 x 400 = 2,800
TO estimate you will round 90 to 100 and round 30 to 50 (or you can leave it be) then 100 X 30 (100 x50) 3000or 50000 :)
overestimate
5 x 4 = 20
Also 38x2=76
38 x 2 =
Simply double every place like so 38x2=30x2+8x2=76
Round 38 to 40. Estimate the product as 80. The actual product is 76.
to find a low estimate for the product of two decimals, round both factors
.100
$3.17
The answer is "Yes sir", and the final product is 3,000 .
round down till there is not a decimal. example: 4.4*5.6 round to 4*5= about 20 (lower estimate)
The answer is 2,800. To estimate the product of 2 numbers, you round to the nearest ten or hundred. In this case, you would round 73 to 70, and 403 to 400, to make it easy to multiply. 70 x 400 = 2,800
5.5 x 3.5 = 19.25
the answer is 70 becuase round 72 to the nearest then it will be 70
