ANSWER TO FRAME 6.

A.

.75

1.875 or 1.88 (Note that we round our answer to two digits to the right of the decimal

point.)

C. .83333 or .83

D. .80

A word about rounding.

As a general rule, carry rounding results just two places beyond or to the right of the decimal

when you finish your computations.

If the third digit is 6, 7, 8, or 9, then raise the second digit to the next higher number.

Thus, 1.876 = 1.88

If the third digit is 5, then raise the second digit if it is odd.

Thus, 1.875 = 1.88

Thus, 1.835 = 1.84

If the third digit is 5, then drop the 5 and do not raise the second digit if it is even.

Thus, 1.865 = 1.86

If the third digit is 0, 1, 2, 3, or 4, then drop that digit and leave the second digit as it is.

Thus, 1.874 = 1.87
