How many 1/8s are there in 3/4​
natka813 [3]

Answer:

there are 6/8 in 3/4

Step-by-step explanation:

if you want to change the denominator of the fraction, you must find the multiple of it,

(3/4) x 2 is 6/8

so you have 6 x (1/8) thats the same 6/8

3/4 is the minimum simplification, if you want to find the same fraction but with other denominator, you have to multiply 3/4 for any number, to do this you have to multiply the numerator and the denominator

Viktor [21]
I'm presuming that the 'large cube' is made from 8 cubes the same size as the 8 cubes in the long row. They both have the same volume, the only difference between them is that they are arranged in a different order. Hope this helps. If not feel free to ask again and give more information.

Varvara68 [4.7K]

<u>Answer: </u>

The population of a city has decreased by 38% since it was last measured. If the current population is 27,900 .Previous population of city was 45000.

<u> Solution: </u>

Given that current population of city is 27900.  

Also, population of a city has decreased by 38% since it was last measured.

Let assume that population of city when it was last measured = x

Decreased of 38% means x-38% of x . we can write this as,

=x-\frac{38}{100} \times x

=\frac{100 x-38 x}{100}

=\frac{62 x}{100}=\frac{31 x}{50}

So current population is \frac{31 x}{50}

Equating above expression to the given value of current population, we get

\frac{31 x}{50}=27900

x=\frac{27900 \times 50}{31}

x=45000

Hence previous population of city was 45000.
