Paul's car is 13 feet long. he is making a model of his car that is 1/7 the actual size. what is the length of the model?
a.
13/7 feet
b.
7/13 feet
c.
14/65 feet
d.
21/52 feet

A. 13/7 feet

Step-by-step explanation:

This is because the length would be 1/7th of 13 feet. That is the 1/7th portion a total of 13 which is obtained by multiplying the fraction by the number to be divided (the actual value of the car)

So in this case, we multiply 13 by 1/7

13 x 1 / 7

= 13/7

Other example for clarity

For instance, if we were making 1/5th the size of the actual model, we would be multiplying 1/5 with the actual value 13 :

13 x 1/5 = 13 / 5

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
