Question

covert the following decimal into per cent
(a) 0.6. (b) 1.8​

Answer 1

A) 0.6

$\sf First \: we \: have \: to \: convert \: into \: \frac{p}{q} \: form.$

$\sf0.6 = \large \frac{6}{10}$

$\sf To \: convert \: into \: percent, \: we \: have \: to \\ \sf multiply \: with \: 100$

$\frac{6}{1 \cancel0} \small \times 10 \cancel0 = 6 \times 10 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \color{red}= 60\%$

B) 1.8

$\sf First \: we \: have \: to \: convert \: into \: \frac{p}{q} \: form.$

$\sf1.8 = \large \frac{8}{10}$

$\sf To \: convert \: into \: percent, \: we \: have \: to \\ \sf multiply \: with \: 100$

$\frac{8}{1 \cancel0} \times 10 \cancel0 = 8 \times 10 \\ \: \: \: \: \: \: \: \: \: \: \: \color{red} \: \: \: \:= 80\%$
