A covered bridge is 6 2/3 yards long. In a painting for sale at a gallery, the bridge is 1 1/4 feet long. A customer wants to know the ratio of the length of the bridge in the painting to the actual length of the bridge. One salesperson says the ratio in simplest form is 3/1. Another salesperson says the ratio in simplest form is 1/16.
The second salesperson is correct. The ratio is 1/16.
In order to find the correct ratio, you first have to turn the actual bridge length into feet. You do this by multiplying the yards by 3.
6 2/3 yards * 3 = 20 feet.
Now we can divide the painting length by the actual length to compare.
1.25ft / 20ft = 1/16
A chess player moves a knight from the location (3,2) to (5,1) on a chessboard. If the bottom-left square is labeled (1,1), the translation made is
You start at (3,2) which means that you are moving 3 squares in the x direction (from 1,1). Chess boards are normally numbered with the home square as (1,1). You are also starting with y = 2. (3,2) is normally occupied by the queen's bishop's pawn. Now you move 2 squares to your right and 1 down towards you. You are now on the king's home square on the first row. This does not entirely follow math rules which caught me when I first read it.
Both moves are translations.

A thick crust with white sauce and garlic. 6. A thick crust with white sauce and cheese. 7. A thin crust with red sauce and mushrooms. 8. A thin crust with red sauce and garlic. 9. A thin crust with red sauce and cheese. 10. A thick crust with red sauce and mushrooms. 11. A thick crust with red sauce and garlic. 12. A thick crust with red sauce and cheese.

Desmond had a savings account. He gave one half of his savings to a charity. He gave 1/4 of his savings to his sister. He then had $20. Left how much did he have before he started giving his money away?
Welcome to Brainly!
Let m represent the amount of money Desmond started out with.
His outgoes were (1/2)m + (1/4)m, or (3/4)m.
Then m - (3/4)m = $20, which works out to (1/4)M = $20.
Multiplying both sides by 4, to remove fractions and solve for m, we get:
(4)(1/4)m = $80. Then m = $80. Desmond started out with $80.
