If f is a factor of n then n/f is also a factor of n is it true or false if true give reason pelase and if false then give counter example thanks.Btw i am in 7 grade please give answer on that behalf...

True

Step-by-step explanation:

Suppose that:

n = fg

here, we can say n, f, and g are positive integers.

the above statement can be read as n is a function of f and g (i.e f and g are factors of n)

Making g the subject of the formula, then:

here, g is said to be the factor of n, since  

We conclude that this statement is true.

15 minutes more, as 60-45mins = 15 minutes.

Step-by-step explanation:

Distance = 30 miles

Speed = 30mph = 1 hr

Compared to Distance 30 miles

Speed = 40mph  = 3/4 of 60mins = 45 mins.

1hr = 60mins = 60-45 = 15 minutes.
