28% is the same as the decimal 0.28, which will be 28/100 as a fraction.

To simplify 28/100 you will have to find what number goes into both this will be 4.

So 28 ÷ 4 = 7

100 ÷ 4 = 25

So Elan will spend 28/100 or if you have simplified 7/25 of his workout on the treadmill.

Answer:

80 countries participated in the 1980 olympics in Moscow.

Step-by-step explanation:

Hello, I think I can help you with this

You can solve this by using a simple rule of three

Step 1

define

140 countries participated in 1984,this was 75% more than the last time,this means that 140 is the 175% of a value that we need to know

140 ⇔175%

x? ⇔100%

the relation is

$\frac{140}{175}=\frac{x}{100}$

Step 2

solve for x

$\frac{140}{175}=\frac{x}{100}\\x=\frac{100*140}{175}\\x=\frac{14000}{175} \\x=80$

80 countries participated in the 1980 olympics in Moscow.

Have a nice day
