Answer:
17.) 12
18.) 1/15
Step-by-step explanation:
2 ÷ 
This problem is asking how many 's can go into 2 blocks. If you divide one box into 6 parts, each tiny box will be of the whole. Divide the other box into 6 parts as well, and you will get 12 of these parts. Check your answer by multiplying 12 by . The answer is 
which is also equal to 2.
÷ 5
For this one, think of it as we have one big box divided into thirds. We want to divide each portion by 5. So you should have 5 tiny boxes in each which gives you a total of 15 boxes. But if we look at it as one big box divided into 15 parts, we know that each of those is 
. Check your answer by multiplying by 5 and you get 
which is equal to .
Let me know if you have any questions, and good luck!
The formula for the slope is 
Hope this helps.

Answer:
288
Step-by-step explanation:
Area of the wall = width x length = 32 x 54 = 1728 sq m
The number of cans for 1 coat = 1728/12 = 144 cans
The number of cans for 2 coats = 144 x 2 = 288 cans
Answer :
x = 53.85
Step by step explanation:
If 78% of x (some numbers) is equal to 42, then we must set this as an equation to find it.
1) Rewriting 78% as a fraction and considering that when we say 78% of some number (x) we mean a product.
78% = 78/100 ➡️ 78/100x = 42
2) Then we can go on :
100 * 78/100x = 42 * 100
78x = 4200
78x/78 = 4200/78 ➡️ x = 53.85
3) Alternatively, simply dividing 42 by 0.78 (78%) would come to the same result :
42/0.78 = 53.85
