2/3y- 2/5 =5

add 2/5 on both sides:

2/3y = 5 + 2/5

Combine the fraction:

2/3y = 5 2/5

Write in improper Fraction:

2/3y = 27/5

Divide both sides by 2/3:

y = 27/5 ÷ 2/3

Change divide fraction to multiplication fraction:

y = 27/5 x 3/2

y = 81/10

Write in mixed number:

y = 8 1/10

Answer: y = 8 1/10

Jason is cutting a roll of sausage into pieces that are 1/2 inches thifk if the roll is 6 inchew long how many pieces of sausage
e-lub [12.9K]

Answer:

12 rolls

Step-by-step explanation:

Jason wants to cut roll into pieces that are each 1/2 inches thick. 1/2 is equal to 0.5, so thickness of each roll is 0.5 inches

Total length of the roll is 6 inches. We have to find how many small 0.5 inch rolls can he cut.

In simple words we can say that we have to find: how many 0.5 inches can be out from 6 inches. This type of problem is solved by division. Dividing 6 inches by 0.5 inches will give us: How many 0.5 inches can be cut out from 6 inches i.e. how many 0.5 inches roll can be made from 6 inches roll

6 divided by 0.5 is 12.

This means Jason can cut 12 rolls of sausages each with thickness of 0.5 inches from a roll of 6 inches.
