Answer:

a) \frac{3}{20} and \frac{16}{20} = \frac{19}{20}

b) \frac{8}{21} and \frac{18}{21} = 1\frac{5}{21}

c) \frac{18}{72} and \frac{32}{72} = \frac{25}{36}

Step-by-step explanation:

a) \frac{3}{20} and \frac{4}{5}

\frac{4}{5} x 4 = \frac{16}{20}

\frac{3}{20} and \frac{16}{20} = \frac{19}{20}

b) \frac{8}{21} and \frac{6}{7}

\frac{6}{7} x 3 = \frac{18}{21}

\frac{8}{21} and \frac{18}{21} = 1\frac{5}{21}

c) \frac{2}{8} and \frac{4}{9}

\frac{2}{8} x 9 = \frac{18}{72}

\frac{4}{9} x 8 = \frac{32}{72}

\frac{18}{72} and \frac{32}{72} = \frac{25}{36}

Sorry another question!
Julli [10]

Answer:

you start counting from left to right

when you want to calculate the difference you have to choose two numbers that are next to each other and subtract second one from first one and because the different between every 2 numbers in order are the same numbers we call it a common difference.

Step-by-step explanation:

for example for 4 :

1. we can choose two numbers next to each other like 1 and 1.1

2. subtract second from first like 1.1 - 1 = 0.1

3. 1.1 + 0.1 = 1.2

1.2 + 0.1 = 1.3

and ...

so the common difference is 0.1
