adoni [48]

Answer:

the previous population was 62,000.

Step-by-step explanation:

The current population of a city = 83,700

The population of a city has increased by 35% since it was last measured.

We have to calculate the previous population before increasing 35%.

Let the previous population be p

p +(35% × p) = 83,700

p + 0.35p = 83,700

1.35p = 83,700

p =  

p = 62,000

Therefore, the previous population was 62,000.

Steven, a tailor, got an order to make a blazer. The customer specifically asked him to save 5⁄6 of a foot of the given cloth to
xz_007 [3.2K]
To answer this question, we just need to subtract the saved cloth from the requested cloth:

\frac{5}{6} - \frac{5}{12}

Since the fractions don't have the same denominator, we have to find the least common denominator.  Luckily, since 6 goes into 12 twice, we can convert \frac{5}{6} into \frac{10}{12}:

\frac{5}{6}( \frac{2}{2}) - \frac{5}{12} = \frac{10}{12} - \frac{5}{12}

Now that the fractions have a common denominator, we can subtract them:

\frac{10}{12} - \frac{5}{12} = \frac{5}{12}

The difference between the requested cloth and the saved cloth is 5/12 of a foot, or 0.4166'.
