Answer
a, $0.54$
b, $0.00619$
c, $1.2\times10^8$
d, $6.7$
Work Step by Step
When determining the correct number of significant figures in the result of multiplication and division calculations, The result of a multiplication or division should carry the same number of significant figures as the factor with the least number of significant figures.
a, $4.5\times0.03060\times0.391$
$0.538407$ will be written as $0.54$
b, $5.55\div897$
$0.00618729097$ will be written as $0.00619$
c,$(7.890\times10^{12})$$\div$$(6.7\times10^{4})$
$117761194$ = $1.17761194\times10^{8}$
$1.2\times10^{8}$
d, $67.8\times9.8\div100.04$
$6.6417433$ will be written as $6.7$
