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}.

in the diagram of parallelogram ABCD shown below the measure of angle A is five times the measure of angle D what is the measure
oksian1 [2.3K]

Answer:

A = 150°

Step-by-step explanation:

In the parallelogram ABCD, A and D are adjacent angles.

We know that in a parallelogram, adjacent angles are supplementary.

Therefore,

A + D = 180° --- (1)

But, it is given that angle A is 5 times angle D.

So, A = 5D

Substitute in (1), we get,

5D + D = 180

6D = 180

D = 30

A = 5D

= 5(30)

= 150

Hence, A = 150°
