Answer:
Step-50*t + 30*m = 1500,   (1)   (pounds)
 4*t +  3*m = 138.    (2)   (cubic feet)
From (2), express 3m = 138 - 4t, and substitute it into (1). You will get
50t + 10*(138-4t) = 1500,  or
10t = 1500 - 1380  --->  10t = 1120  --->  t = 112 TVs.
From this point, find the number of microwaves on your own.

Answer:
3/8
Step-by-step explanation:
3 1/3 = 10/3 
1 1/4 = 5/4
Remember when dividing by a fraction you can also multiply by its reciprocal meaning flip the numerator and denominator. 
so
(3 1/3) / (1 1/4) = (10/3) / (5/4) = (10/3) x (4/5) which is the same as (3/10) x (5/4)
= (3 x 5) / (10 x 4) = 15 / 40
the numerator and denominator have a common factor of 5 so divide the  numerator and denominator by 5
15 / 40 = 3/8
