3:5 =3/5
3/5=4.16/x
using cross multiplication,
5(4.15)=3(x)
20.8=3x
x=108/15
thus, 4.16÷104/15 =3/5
70 = 50 * x/100
x = 70/50*100 = 140
Seventh is 140% of 50.
2^4-1 so 2•2•2•2=16 and 16-1 is 15
168,356. the ten thousand is the 6. To find the estimate, the one would stay there and the six would become a seven because the eight eight before the six is above five. All in all, the answer is 170.000
