The person HAD homework 75/100 or 75%

the remaining days he did NOT have homework , which is 25/100 or 25%

Basically the question states that the student had homework 75% of the time. Or 75/100 of the time. They are the same. So to figure out when the student did not have homework you would subtract 100-75. So 25% or 25/100.

nalin [4]

Answer:

$80^{\circ} C$

Step-by-step explanation:

You are making rusks and have to dry them overnight at a temperature of 176° F.

The given temperature is in Fahrenheit. We need to convert it into °C.

The relation between Fahrenheit and °C is given by :

$C=\dfrac{5}{9}(F-32)$

Put F = 176

So,

$C=\dfrac{5}{9}(176-32)\\\\C=\dfrac{5}{9}\times 144\\\\C=80^{\circ} C$

So, the temperature is equal to $80^{\circ} C$ .
