Round each of the numbers then add the rounded numbers. 60+40=100.
The idea is to round each of the numbers - in this case to the nearest multiple of 10 - then do the addition in your head.
43.
43 minus the sum of 16 and 11 can be calculated as follows: 16 + 11 = 27 43 - 27 = 16 Therefore, 43 minus the sum of 16 and 11 is equal to 16.
The two numbers with the sum of 15 and the product of 56 are: 7 + 8 = 15 7 x 8 = 56
43 is the sum of the two consecutive integers 21 and 22.
The idea is to round each of the numbers - in this case to the nearest multiple of 10 - then do the addition in your head.
To estimate the sum of 56 and 58, you can round both numbers to the nearest ten. Rounding 56 to 60 and 58 to 60 gives you an estimated sum of 120. Therefore, the estimate of 56 plus 58 is approximately 120.
56 is estimated to be 60.
43% of 56 is 24.08
43 + 56 = 99
% rate = 43/56 * 100% = 130.23
56 feet by 43 feet = 56*43 = 2408 sq feet
43.
% rate = 56/43 * 100% = 130.24%
56-13 = 43
43
To find the sum of -27 and 43, you can add the two numbers together. -27 + 43 = 16 Therefore, the sum of -27 and 43 is 16.
