Question

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

(1.74)(9.95)(3.46)

A.
80

B.
72

C.
60

D.
54

FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFUUUUUUUUUUUUUUUU

Answer 1

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
therefore
the product p = abc becomes
"approximately" :

P = A x B x C = 2 x 10 x 4 = 80

Answer 2

Wait! I rounded to the wrong number. c=3
So, P = A x B x C = 2 x 10 x 3= 60

Answer 3

ok thanx
