To round to estimate the product of 38 x 2, you first round each number to a more manageable value. In this case, you can round 38 to 40 and 2 to 0. Then, multiply the rounded numbers together to get an estimate of the product. In this case, 40 x 0 = 0. So, the estimated product of 38 x 2 is 0.
90000 x 40 = 3600000
33 x 38
40 x 30 = 1200
They are: 33 times 38 = 1254
If that's 16 and 38, it could be estimated as 15 x 40 = 600
40% of 38 = 38*40/100 = 15.20 dollars
38
38 x 40 = 1,520
yes the pattern of multiplying binomials. 42 = (40 + 2) and 38 = (40 - 2) so 42 x 38 = (40 + 2)(40 - 2) => use the pattern of the difference of squares = 402 - 22 = 1600 - 4 = 1596
95% 38/40
The HCF of 38 and 40 is 2
