4 of the original boards have a summed length of 20 units. 5 x 4 = 20.
Since 2/5 is left from each board, you simply add them until the 2's add to 20.
So, 2 x 10 = 20. Hence, there are 10 2/5 boards.
That's just 4 of the boards that the 2/5 make up, but that should also mean that there are 10 3/5 boards as well.
30/5 + 20/5 = 50/5
Reduction = 10
The carpenter started with 10 5/5 boards.

Always go from left to right as compare the values in the tenth, then hundredths, then thousandths place. Remember that if there is no digit, it is a 0 (after the decimal of course).
Answer:
Yes, they are equivalent.
Step-by-step explanation:
- To see if they're equivalent, you have to solve them. Start with the first one. Steps are below.
- Apply the distributed property: 8 + 12
- 8 + 12 = 20
For second expression:
- 4(2) = 4 × 2 = 8
- 4(3) = 4 × 3 = 12
- Put them together: 8 + 12
- 8 + 12 = 20
Making a conclusion:
Because they both have the same answer, they are equivalent expressions.
I hope this helps!
Answer:
Ok i can try to answer it
Step-by-step explanation:
(8 2/3) / (2/3) = x / 1....8 2/3 miles to 2/3 hr = x miles to 1 hr
cross multiply
(2/3)(x) = (8 2/3)(1)
2/3x = 26/3
x = 26/3 * 3/2
x = 26/2...which equals 13....she will ride 13 miles in 1 hr
