Lets see... of the 50 states 4 have the letter W so that would make the fraction

since percents are out of 100 , you would multiply both numbers by 2 making the percent of letter W's
8% . Hope it helps!!
So 45 in 30mins
we ususlly want to make the smallest number equal to one or as close to one as possible so
45/30=3/3 times 15/10
3/3=1
1 times 15/10=15/10
15/10=5/5 times 3/2
5/5=1
1 times 3/2=3/2
3 divided by 2 is 1.5
1.5 flowers per minute
put it into an equation..
15+5v
sum is addition and product is multiplication
The circumference of the circle is about 25.12 inches. Hope it help!
