The old man walked 2/3 of a mile in 1/2 of an hour. What is this rate in miles per hour?

1 answer:

7 0

If the old man walks 2/3 of a mile in 1/2 an hour, you can find how many miles he walk in one hour by setting up a fraction where distance (miles) is the numerator and the denominator is time (hours). So, (2/3)/(1/2) is the fraction. Now, we have to figure out how to make the denominator one, and we do that by multiplying is by 2. Whatever you do to the denominator you have to do to the numerator, so multiply 2/3 by 2 and 1/2 by 2.

(1/2) x 2 = 1 and (2/3) x 2 = 4/3 or 1 1/3

the old man walked 1 1/3 miles per hour

m_a_m_a [10]

Answer:

75 small triangles

Step-by-step explanation:

1. Reduce the ratio: 2-6 = 1-3

2. Write each of them as a fraction of a whole:

Small total = 3/(1+3) = 3/4 of the total amount

3. Multiply the ratio to get the answer: 3/4 * 100 = 75

PLEASE HELP ME ...........Julie was looking at the architect's blueprint of her house. The scale on blueprint was 1/4 inch = 1 f

MAVERICK [17]

Answer:

On the blueprint the dimensions are 48 inches by 64 inches.

Step-by-step explanation:

Given:

The scale on blueprint was 1/4 inch = 1 foot.

The actual dimensions of her bedroom are 12 feet by 16 feet.

Now, to find the dimensions on the blueprint.

Let the dimensions on the blueprint be $x$ by $y.$

As, given the scale on blueprint:

$\frac{1}{4}\ inch=1\ foot$

So, $\frac{1}{4}\ inch$ is equivalent to 1 foot.

Thus, $x$ is equivalent to 12 feet.

And, $y$ is equivalent to 16 feet.

Now, solving by cross multiplication method:

$\frac{\frac{1}{4}}{1} = \frac{x}{12}$

$\frac{4}{1} =\frac{x}{12}$

By cross multiplying we get:

$48=x$

$x=48\ inches.$

Now, again:

$\frac{\frac{1}{4}}{1} =\frac{y}{16}$

$\frac{4}{1} =\frac{y}{16}$

By cross multiplying we get:

$64=y$

$y=64\ inches.$

Therefore, on the blueprint the dimensions are 48 inches by 64 inches.
