Question

The speed thing above the chart, Ya pretend that is not there

Answer 1

`a=10\%\\\\b=(25)/(100)\\\\c=(1)/(2)`

Explanation:

To find "a" you can multiply
`(10)/(100)` by 100, then this is:

`a=(10)/(100)*100\\\\a=10\%`

To find "b", you can multiply the numerator and the denominator of the fraction
`(1)/(4)` by 25, getting:

`b=(1*25)/(4*25)\\\\b=(25)/(100)`

To find "c", you can reduce the fraction
`(50)/(100)`. Then you get that this is:

`c=(50)/(100)\\\\c=(25)/(50)\\\\c=(5)/(10)\\\\c=(1)/(2)`

Answer 2

For this case we have:

a)

`\frac {1} {10}`to convert as a percentage we have:

`\frac {1} {10}` * 100% = 10%

b)

`\frac {1} {4}`, if we multiply the numerator and denominator by 25 we have:

`\frac {25} {100}`

c)

Now we must write a fraction that represents 50%.

We have
`\frac {1} {2}`. If we multiply the numerator and denominator by 50 we have:

`\frac {50} {100}`

Answer:

10%

`\frac {25} {100}\\\frac {1} {2}`
