Step-by-step explanation:
16%of 450=16/100×450
(cancel the 0 that is common)
=16/10×45
=1.6×45
=72
There are 72 blue marbles
32%of 450=32/100×450
(cancel the zero that is common)
=32/10×45
=3.2×45
=144
There are 144 white marbles
28%of 450=28/100×450
(cancel the common zeros)
=28/10×45
=2.8×45
=126
There are 126 green marbles
Red marbles persentage =addition of the remaining marbles subtracted from 100.
=16%+32%j28%-100
=76-100
=24%
24% of 450=24/100×450
(cancel the common zeros)
=24/10×45
=2.4×45
=108
there are 108 marbles
so 72+144+126+108=450
