Answer:
He'll be able to make 6 shelves.
Step-by-step explanation:
In order to know haw many shelves he can make we need to take the total amount of material and divide it by the amount of material required for each shelve. We have:
total amount = 83 1/2 inches = 83.5 inches
amount per shelve = 12 3/4 inches = 12.75 inches
amount of shelves = total amount/amount per shelve
amount of shelves = 83.5/12.75 = 6.55 shelves
Since he can't make half shelves he'll be able to make 6 shelves and have left over material.
Answer:
12x
Step-by-step explanation:
10 +2 =12
12+x=12x
Now, in order for it to be a proportion, both the number and the denominator must turn to the other number by the same method. I'll clarify when we do the steps.
So, the first one is 4/10 and 10/25
The first thing that you would do is divide 10 by 4, and then 25/10
When you do that, it turns out that they both equal 2.5. This means that both the number and denominator go to the new number with the same method, multiplying by 2.5
So, the answer would be A
You have to make the fractions an improper fraction. For 4 3/4 first multiply 4x4 which is 16 then 16+3 which is 19/4. For 2 2/3 multiply 3x2 which is 6 then 6+2 which is 8/3. Now make 19/4 and 8/3 denominators same. 19/4 becomes 57/12 by multiplying 19x3 which is 57 and 4x3 which is 12. 8/3 becomes 32/12 by multiplying 8x4 which is 32 and 3x4 which is 12. Then add 57/12+32/12 which is 89/12. Now make 89/12 into a mixed number. The mixed number is 7 5/12.
Hope that helped:)
