Answer: 7/12 portion
Explanation:
Jack can paint:
1 house = 3hr
1/3 portion= 1hr
Jill can paint:
1 house = 4hr
1/4 portion = 1hr
Both of them together can paint in 1 hour:
1/3 + 1/4 = 3/12 + 4/12 = 7/12 portion in 1hr
Answer: 32 divided by 4 = 8
Step-by-step explanation:
If the diagram is 8 ovals with 4 squares each, and we know that this is a division, then we have that an unknown number X is such that:
X/4 = 8
this is because we know that the division is by 4 (the number of squares in each oval) and the solution of the division is the number of ovals.
Then we can solve the equation for X.
X/4 = 8
We multiply each side of the equality by 4
X = 4*8 = 32
Then the diagram represents the division:
32/4 = 8 or " 32 divided by 4 = 8"
