Answer:

Solve 14×1/5=n does not work

Step-by-step explanation:

Assuming you mean

4 ÷ 1/5=n

A Find out how many 1/5s are in 4.

That is correct. We are writing the division problem in words

B Solve 4×5/1=n.

We can copy dot flip

4 * 1/5=n

C Solve 1/4×1/5=n.

We do not flip the first term

D Solve n×1/5=4.

4 ÷ 1/5=n

Multiply each side by 1/5

4 ÷ 1/5 * 1/5=n* 1/5

4 = n*1/5

Answer:

Step-by-step explanation:

w + 1/2 ➡ (2w + 1)/2

w/4 + 2➡ (w + 8)/4

(2w + 1)/2 = (w + 8)/4

8w + 4 = 2w + 16 ➡ 6w = 12

w = 2

Ruben put an empty cup underneath a leaking faucet. After 1 1/2 hours, Ruben had collected 1/4 cup of water. What is the rate, i

worty [1.4K]

Answer:

The rate is $\frac{1}{6}$ cups per hour

Step-by-step explanation:

It took the faucet 1 1/2 hours, i.e 1.5 or 3/2 hours to fill 1/4 cup by leaking

We need to find the rate in terms of cups that can be filled by water in 1 hour.

Using unitary method:

If it takes $\frac{3}{2}$ h for $\frac{1}{4}$ cup;

then it will take 1 h for how many cups?

$= \frac{1 \times \frac{1}{4} }{\frac{3}{2} }$

$= \frac{2}{4 \times 3}$

$= \frac{2}{12}$

$= \frac{1}{6}$ cups

Therefore, the rate is $\frac{1}{6}$ cups per hour
