Lemur [1.5K]

Answer:

Step-by-step explanation:

Your question isn't complete but let me help out based on the information given.

Joshua's recipe for chili requires 2 3/4 ​ pounds of beef. Sondra's recipe for chili requires 2 2/3 ​ pounds of beef.

The pounds of beef required by both of them will be:

= 2 3/4 + 2 2/3

= 2 9/12 + 2 8/12

= 4 17/12

= 4 + 1 5/12

= 5 5/12

The difference in the pounds of beef required by both of them will be:

= 2 3/4 - 2 2/3

= 2 9/12 - 2 8/12

= 1/12

Also, we.can also infer that Joshua recipe for chili requires more pounds of beef than that of Sondra

A closet containing 120 pieces of clothing is made
lapo4ka [179]

Answer:

5/9

Step-by-step explanation:

Let's define:

  • sw: number of sweaters
  • j: number of jeans  
  • sk: number of skirts

The following three equations are established from the question:

sw + j + sk = 120

sw/j = 8/3

j/sk = 3/4 or sk/j = 4/3

Dividing the first equation by j, we get:

sw/j + j/j + sk/j = 120/j

8/3 + 1 + 4/3 = 120/j

5 = 120/j

j = 120/5 = 24

sw = 24*8/3 = 64

sk = 24*4/3 = 32

After the replacement the new number of jeans and skirts are:

j' = 24 - 4 = 20

sk' =  32 + 4 = 36

the new ratio of jeans to skirts is:

j'/sk' = 20/36 = 5/9
