$70 %$ $70%$

24 is 30% of 80

$(\frac{24}{80} = \frac{3}{10} = 30 %)$ $(24/80=3/10=30%)$

Change = 100% -30% = 70%

$70 %$ $70%$

The percent decrease or increase can be calculated from:

$\frac{amount of the change}{original amount} \times 100 %$ $("amount of the change")/("original amount") xx 100%$

In this case the change was from $80 \to 24$ $80 rarr 24$

$80 - 24 = 56$ $80-24 = 56" "$ It was a decrease of 56.

$\frac{56}{80} \times 100 %$ $56/80 xx 100%$

= $70 %$ $70%$
