the improper fraction is 27/7
To convert the mixed number 3 6/7 to an improper fraction, we need to combine the whole number part with the fractional part.
First, multiply the whole number (3) by the denominator (7), which gives us 21. Then, add the numerator (6) to get 27.
Next, write the sum (27) as the numerator and keep the denominator (7) the same. The resulting improper fraction is 27/7.
This means that there are 27 parts (numerator) out of 7 equal parts (denominator). The improper fraction emphasizes the total number of parts beyond a whole number.
Converting the mixed number 3 6/7 to the improper fraction 27/7 allows for easier mathematical operations and comparisons with other fractions.
Therefore, the improper fraction is 27/7

The solution is, Actual distance between point C and D is 900m.
What is ratio?
The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
here, we have,
given that,
The distance between City A and City B is 500 miles.
A length of 1.9 feet represents this distance on a certain wall map.
City C and City D are 3.42 feet apart on this map.
Let, x be the actual distance between point C and D
Using ratio method,
1.9 : 500
3.42 : x
Now, we get,
1.9/500= 3.42/x
i.e. 3.42/x = 0.0038
or, x = 3.42/ 0.0038
or, x = 900
so, we get,
x=900
Actual distance between point C and D is 900m.
