Mathematics

Thepotemich [5.8K]4 years ago

Answer:

The least common denominator is 21.

Step-by-step explanation:

First, you must find the least common factor of the two:

3: 3, 6, 9, 12, 15, 18, <em><u>21</u></em>, 24, 27, 30

7: 7, 14, <em><u>21</u></em>, 28, 35, 42, 49, 56, 63, 70

Second, you must increase the fractions:

\frac{1}{3} × \frac{7}{7} = \frac{7}{21}           \frac{3}{7} × \frac{3}{3} = \frac{9}{21}

You and your friends compare how many
Helen [10]

answer:

the mean for this is 27

step-by-step explanation:

all you have to do is add up all of the times

15, 18, 20, 22, 28, 37, 49

which would have given you

189

then you divide that number by how much times were written down

7 would be that number so

189/7 = 27

and this is what it is written in one equation

(15+18+20+22+28+37+49)/7

hope this helps you! :)
