we know that

The number 80 represent the 100%

<u>Find the percentage of the number 64</u>

by proportion

\frac{80}{100}   =\frac{64}{x}  \\\\    80*x=64*100

x=\frac{64*100}{80}

x=80%

<u>Find the percentage decrease</u>

Percentage decrease=100-80=20%

therefore

<u>the answer is</u>

The percentage decrease is equal to 20%

If q, s, and t are all different numbers, is q &lt; s &lt; t ?
inessss [21]
It very well could be, but not necessarily. What if q = 10, s = 8, and t = 6?

The statement is that q is less than s, and s is less than t (which therefore also means q is less than t).

However, when we substitute (replace) all the letters with the values we assigned them, we can find that the expression becomes:

10 < 8 < 6

This clearly isn’t right, as 10 is the greatest number there, and 8 is definitely less than 10 and greater than 6.
