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.
Round each of the numbers then add the rounded numbers. 60+40=100.
The two numbers with the sum of 15 and the product of 56 are: 7 + 8 = 15 7 x 8 = 56
Their sum is 56.
you put the numbers in order from least to greatest, then u look 4 the middle
The answer is 7. Seven squared is forty nine. 49 plus 7 equals 56.
Round each of the numbers then add the rounded numbers. 60+40=100.
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 + 56 = 99
43% of 56 is 24.08
56+26 = 82
% rate = 43/56 * 100% = 130.23
56 feet by 43 feet = 56*43 = 2408 sq feet
% rate = 56/43 * 100% = 130.24%
56-13 = 43
43
the only two odd numbers are 57 and 59 which give a sum of 116
