Question 18 Find the sum in reduced form. 2 5 + 2 3

Mathematics
1 answer:
Kobotan [32]3 years ago
7 0

Answer:


Step-by-step explanation:

Those are fractions, are they not? I'll treat them that way.

\dfrac{2}{5}+\dfrac{2}{3}

Find the lowest common denominator.

You need 1 three and 1 five.

2/5 = (2*3)/(5 * 3) = 6 / 15

2/3 = (2*5)/(3*5) = 10 /15

\dfrac{2}{5}+ \dfrac{2}{3}= \dfrac{6}{15}+\dfrac{10}{15}

\dfrac{2}{5}+ \dfrac{2}{3}=\dfrac{16}{15}   Just add the numerators.

It is reduced. There are other ways to write it

16/15 = 1 1/15 is one of them

Can someone please answer this ?

We need to know the density of Marble City, hence we know the density of Pebble City.
MC density = population/area
MC density = 52,348/125
MC density = 418.784 people/miles

From the question, we know that the two cities have the same population density.
PC density = MC density
PC density = 418.784 people/miles

Use the density formula to figure out the dimension of PC
PC density = population/area
418.784 = 85,312/(l × w)
(l × w) = 85,312/418.784
11.8 w = 85,312/418.784
11.8 w = 203.7
w = 203.7/11.8
w = 17.2

The closest value of x is 17 miles
