Question

Estimate the value of this expression by rounding each number to the nearest whole unit.



(1.74)(9.95)(3.46)



A.
60


B.
80


C.
72


D.
54

Answer 1

The only possibility I see, consists in rounding each number
up to its nearest integer number, so
a = 1.74 is rounded up to A = 2
b = 9.95 is rounded up to B = 10
c = 3.46 is rounded up to C = 4
P = A x B x C = 2 x 10 x 4 = 80

The second answer would be the correct.
