How can you tell when a pattern shows counting on by tens?

Answers

Answer:
The difference between successive terms is 10

Explanation:
To know the factor by which a certain pattern is increasing/decreasing, you need to subtract its successive terms.

If the subtraction gives you 10, this means that the pattern is increasing by 10

Examples:
10, 20, 30, 40, 50, .....
20 - 10 = 10
30 - 20 = 10
40 - 30 = 10
50 - 40 = 10
The difference between each two successive terms is 10. This means that each time we add 10 to the number we have in order to get the next one.
Therefore, this pattern is increasing by 10

37, 47, 57 , .....
47 - 37 = 10
57 - 47 = 10
The difference between each two successive terms is 10. This means that each time we add 10 to the number we have in order to get the next one.
Therefore, the pattern is increasing by 10

Johan buys three flats of flowers he plants 2/5 of the flowers and then divides the remaining flowers amongst five friends. What fraction of the flat of flowers does each of Johahn's friends get?

Answers

Answer:

Each friend will get $(9)/(25)$ of the flat of flowers.

Step-by-step explanation:

Johan buys 3 flats of flowers.

He plants $(2)/(5)$ th of the flowers, then the remaining flowers = 3 - $(2)/(5)* 3$

= $(9)/(5)$

Now he divides the remaining flowers among 5 friends.

So each friend gets the fraction of flowers = $\frac{\text{Remaining flowers}}{\text{Number of friends}}$

= $((9)/(5) )/(5)$

= $(9)/(25)$

Therefore, each of Johan's friend will get $(9)/(25)$ of the flat of flowers.

We have to calculate the remaining, or the supplanted flower fraction.
Remaining =1-2/5=(5-2)/5=3/5.

Now, we calculate the fraction of the flat of flowers get by each friend.

Fraction get by each friend=remaining/number of friends
Fraction get by each friend=(3/5)/5=3/25

Answer: 3/25 flat of flowers are got by each friend
