It would take her 10 hours. If it is double the time for one person to complete the task versus two, you can guess that the other person takes the same amount of time

Answer:

C) \frac{2}{4}, \frac{2}{3}, \frac{7}{10}, \frac{4}{5}

Step-by-step explanation:

Given fractions:

\frac{2}{4}, \frac{4}{5}, \frac{7}{10},\frac{2}{3}

To arrange the fractions from least to greatest.

Solution:

In order to arrange the fractions from least to greatest, we need to make the denominators common by taking LCD.

LCD of 4,5,10,3 can be found using their multiples.

4= 4,8,12,16,20,24,28,32,36,40,.........60

5= 5,10,15,20,25,30,.........60

10= 10,20,30,40,50,60

3= 3,6,9..........................60

So, 60 is the LCD.

Making the denominators common by multiplying same numbers to numerator and denominator.

\frac{2}{4}=\frac{2\times 15}{4\times 15}=\frac{30}{60}

\frac{4}{5}=\frac{4\times12}{5\times 12}=\frac{48}{60}

\frac{7}{10}=\frac{7\times 6}{10\times 6}=\frac{42}{60}

\frac{2}{3}=\frac{2\times 20}{3\times 20}=\frac{40}{60}

Comparing the numerators we can arrange the fractions.

\frac{2}{4}, \frac{2}{3}, \frac{7}{10}, \frac{4}{5}

A 6 month old sheltie puppy gets 2.5 cups of food twice per day. Select the equation that describes how many cups of food she ea
Molodets [167]

Answer:

y = 5x

D is the correct option.

Step-by-step explanation:

We have been given that sheltie puppy gets 2.5 cups of food twice per day.

It means that in a day she eats 5 cups of food. It means the rate is 5 cups of food per day.

The equation will be linear.

Let y be the number of cups of food she eat and x is the number of days.

Hence, we have

Slope = 5

And the equation that represents the number of cups of food she eats is given by

y = 5x

D is the correct option.
