Cual es la simplificacion de 66/81
Karo-lina-s [1.5K]

Answer:

Hence the simplification of \dfrac{66}{81} is \dfrac{22}{27}

Step-by-step explanation:

<em>" Simplification is the process of replacing a mathematical expression by an equivalent one, that is simpler (usually shorter), </em>

<em>for example</em><em>: Simplification of a fraction to an irreducible fraction ". </em>

Here we are given a fraction as:

\dfrac{66}{81}

As both the numerator and denominator are divisible by a factor of 3 hence we take out the common factor and obtain the reduced fraction which is further irreducible.

As 66=3×22  and 81=3×27

Hence \dfrac{66}{81}=\dfrac{3\times22}{3\times27}=\dfrac{22}{27}

Hence the simplification of \dfrac{66}{81} is \dfrac{22}{27}

750 split in to the ratio 7:8
Alex787 [66]
Given:
total = 750
ratio = 7 : 8

We need to get the ratio of the number to its total

7 + 8 = 15 ; 7/15 and 8/15 is the ratio of the number to its total.

We multiply these ratio to the total of 750

7/15 * 750 = 350
8/15 * 750 = 400

7:8 is equal to 350:400
