What is the simplest form of ratio 11:16
vitfil [10]

Answer:

Actually 11:16 is the answer

Step-by-step explanation:

we have to divide both terms by 1. because there is no other number that can go into 11

11 ÷ 1 = 11

16 ÷ 1 = 16

Since GCF = 1 we cannot reduce the ratio any further so:

11 : 16 = 11 : 16

Rational expression. simplify<br> 36m-48m over 6m.
ladessa [460]
One way is to find common factors

example

8/6=4/3 because 8/6, 8 and 6 have common factor of 2 so divide that out to get 4/3
basically divide the LCM from each

so factor

we can combine 36m-48m into -12m
we have
-12m/6m

common factor is 6m
-12m/6m=(-2)/1 times (6m)/(6m)=-2 times 1=-2

answer is -2
