Answer:
1 5/12 lb
Step-by-step explanation:
This is a subtraction problem.
He started with 4 2/3 lb and used 3 1/4 lb, so you need to subtract 3 1/4 lb from 4 2/3 lb.
Notice that the fractions do not have the same denominator, so we need a common denominator and equivalent fractions.
We start with the
subtraction below
4 2/3
- 3 1/4
---------------
The least common denominator of 3 and 4 is 12. 12/3 = 4, and 12/4 = 3, so we get equivalent fractions with the common denominator 12.
We use the LCD to get
the subtraction below
4 8/12
- 3 3/12
----------------
Now we subtract the whole numbers and the fractions.
4 8/12
- 3 3/12
----------------
1 5/12
Answer: 1 5/12 lb
Answer:
Basically, you have to think: more bricks : more time
more workers : less time
2,400 bricks 6 workers takes 18 hours
You now have to solve for 4,500 blocks and 10 workers
4,500 / 2,400 = 1.875 (times greater)
10 / 6 = 1.666666666 (times less)
So, we get 18 hours, multiply it by 1.875 and divide it by 1.666666666
which equals 20.25 hours
So, it seems you were correct on your third try.

Answer:
13 and three-fourths inches
Step-by-step explanation:
The map distance can be found using a proportion with the map scale.
__
map distance / (1100 mi) = (1 in) / (80 mi)
map distance = (1100×1)/80 in = 13 3/4 in . . . multiply by 1100 mi; cancel mi
The trip will be about 13 3/4 inches on the map.
