Answer:

\cfrac{7}{6}

Step-by-step explanation:

\cfrac{7}{8} \div \cfrac{3}{4}

Divide 7/8 by 3/4 by multiplying 7/8 by the reciprocal of 3/4:

\cfrac{7}{8}\times \dbinom{4}{3}

Now, multiply 7/8 times 4/3 by multiplying numerator times numerator and denominator times denominator:

\cfrac{7\times 4}{8\times 3}

Do multiplication in fraction: \cfrac{7\times 4}{8\times 3}

\cfrac{28}{24}

Reduce fraction \frac{28}{24} to lowest terms by extracting and canceling 4 out:

\cfrac{7}{6}  \checkmark

Three numbers are in the ratio 3:9:10. If 10 is added to the last number, then the three numbers form an arithmetic progression.
MrRa [10]

Answer:

<em> The numbers are 6, 18, and 30 </em>

Step-by-step explanation:

If the three numbers are in the ratio of 3:9:10,

let the numbers be 3x, 9x and 10x.

<em>If 10 is added to the last number to form an arithmetic progression</em>

<em>Then, 3x 9x (10x+10) are the progression</em>

The common difference of an arithmetic progression (d) = T₂ - T₁ = T₃ - T₂

T₂-T₁ = T₃ - T₂ .............. Equation 1

Where T₁ = first term of the progression, T₂ = Second term of the progression, T₃ = third term of the progression

<em>Given: T₁ = 3x, T₂ = 9x, T₃ = 10x +10</em>

<em>Substituting these values into equation 1</em>

<em>9x-3x = (10x+10)-9x</em>

<em>Solving the equation above,</em>

<em>3x = 10+x</em>

<em>3x-x = 10</em>

<em>2x = 10</em>

<em>x = 10/2</em>

<em>x = 2.</em>

<em>Therefore the numbers are 6, 18, and 30 </em>
