round 38 to 40 and get 80 by multiplying. Then, do 38 x 2 and you’d have to round to get about the same answer.
4x + 10 = 384x = 38 - 104x = 28x = 28/4Therefore, x = 7.
38% of 250 = 95 you do this by multiplying 0.38 (for the 38%) times the 250 and it will give you 95. this works for any number
38 times. 76/2 = 38
To determine how many times 38 goes into 360, you would divide 360 by 38. The result of this division is approximately 9.4737. Since you cannot have a fraction of a division, you would need to round down to the nearest whole number. Therefore, 38 goes into 360 approximately 9 times.
53/7 * 28 = 38/7 * 28 = 38*4 = 152
Call the unknown number n. Then, from the problem statement, 9n - 7 = 38, or 9n = 45, or n = 5.
The percent increase, X, of a number A to number B is X = (B-A)/A times 100 X = (38-29)/ 29 x 100 = 31%
38.5 x 8 = 308
646 = 17 times 38.
It is: 8/21 times 100 = 38% as a whole number
38 and 190
