Question

If there are 39900000 flowers, how many are blue at 1.8% and how many are dotted at 11.5%, how many are blue and dotted?

Answer 1

Total # of flowers: 39,900,000

1.8% are blue

11.5% are dotted

# of blue dotted flowers: ?

BLUE) 1.8/100 = x/39900000

100x=1.8(39900000)

100x/100 = 71820000/100

x=718200 blue flowers

DOTTED) 11.5/100 = x/39900000

100x=11.5(39900000)

100x/100 = 458850000/100

x=4588500 dotted flowers

blue dotted= 39900000-(blue+dotted)

blue dotted = 39900000-(718200+4588500)

blue dotted = 39900000-(5306700)

blue dotted = 34,593,300 flowers

ANSWER: blue flowers = 718,200

dotted flowers =4,588,500

blue dotted flowers =34,593,300
