Mixed number is a natural number plus a proper fraction
a mixed number, is normally more than 1
anyway
percent means parstt out of 100
0.55%=0.55/100=0.055/10=0.0055/1=0.0055
it is 55/10000 as a fraction or 0 and 55/10000 aas a mixed number
decimal it is 0.0055
Equation is y=kx. We have four chance to figure out k; hopefully they all give the same result
x=9, y=63, y=kx becomes 63=k(9) so k=63/9=7
x=4, y=28, 28=k(4), k=7
The constant of proportionality is 7; we check 2×7=14, 11×7=77
Answer: k=7, y=7x
Create and solve an equation of ratios:
10 ft 8 oz
------- = -------
x 48 oz (note that 3 lb = 48 oz)
Then 480 = 8x, and x = 60 ft (answer)
3y - 1 = 28
+ 1 + 1
----------------
3y = 29
---- ----
3 3
y= 9.66
