round 61.373737842 to the nearest ten-millionth?

Answer 1

61.3737378

Ten-millionth = 1/10,000,000 = 0.0000001

So round to 7 decimal places (number of zeroes in 10 million or position of 1 after the decimal in 0.0000001). Always look at the next digit, to determine if you round up or down. In this case, the next digit is 4, so we round down.

If you have trouble remembering the number of digits, start with:
Nearest tenth (0.1) = 1 digit:
61.4
Nearest hundredth (0.01) = 2 digits:
61.37
Nearest thousandth (0.001) = 3 digits:
61.374
Nearest ten-thousandth (0.0001) = 4 digits:
61.3737
Nearest one-hundred-thousandth (0.00001) = 5 digits:
61.37374
Nearest millionth (0.000001) = 6 digits:
61.373738
Nearest ten-millionth (0.0000001) = 7 digits:
61.3737378
