Question

The price of an item yesterday was 110. Today the price fell to 33 find the percentage decrease

Answer 1

110-100%
33-x
X=30
100-30=70% is the answer

Answer 2

The amount of the decrease is    (110 - 33) = 77

The decrease as a fraction of the original amount is  ( 77 / 110 ) .

As a decimal,  77/110 = 0.7 .

To change a decimal to a percent, move
the decimal point two places that way  ==> .

                                 0.7  ==>  70% .
