2 2/3 of what number is 6 1/7

borishaifa [10]

$2\frac{2}{3}$ of $2\frac{17}{56}$ is $6\frac{1}{7}$

Solution:

Given $2\frac{2}{3}$ of what number is $6\frac{1}{7}$ .

Let us first convert the mixed fraction into improper fraction.

$$2\frac{2}{3}=\frac{(2\times3)+2}{3}=\frac{8}{3}$

$$6\frac{1}{7}=\frac{(6\times7)+1}{3}=\frac{43}{3}$

Now, let us take the unknown number be x.

$$2\frac{2}{3}\times x=6\frac{1}{7}$

$$\frac{8}{3}\times x=\frac{43}{7}$

Do the cross multiplication.

$$ x=\frac{43}{7}\times\frac{3}{8}$

$$ x=\frac{43\times3}{7\times8}$

$$ x=\frac{129}{56}$

Now, again change the improper fraction into mixed fraction.

$$ x=2\frac{17}{56}$

Hence $2\frac{2}{3}$ of $2\frac{17}{56}$ is $6\frac{1}{7}$ .

Jared and Pedro walk 1 mile in about 15 minutes. They can keep up pace for several hours. About how far they walk in 65 minutes

VladimirAG [237]

<h2>Answer:</h2>

Jared and Pedro walked a total of 4.3 miles

<h2>Step-by-step explanation:</h2>

The equation for distance is speed = distance ÷ time.
Rearrange the equation to make distance the subject:

(multiply both sides by time)

Distance = Speed × Time

Convert your numbers into suitable units:

1 mile ÷ 15 = 0.06m/minute

Finally, substitute the numbers into the equation and solve:

Distance = 0.06 × 65 = 4.3miles (rounded to the nearest decimal place)
