Count pennies by 2. Write the missing numbers.

Answer:

Explanation:

The difference between the first and second pennies is 2⊄ also second and third pennies is 2⊄. So, the fourth pennies are increased by 8⊄ which means 6⊄ + 2⊄ =8⊄. The missing numbers in the given sequence are 8⊄, 10⊄, 12⊄.

Count by 2. Start at 80⊄. Write the missing numbers.

Answer:

Explanation:

First coin score is given as 80⊄. It was given that the score of second coin is 82⊄ which is expected. If we count by 2⊄, then a 2⊄ should be added to the second coin score to get the third coin which means 82⊄ +2⊄ =84⊄. It was given that the score of fourth coin is 86⊄ which is expected. Now, for the fifth coin, we need to add 2⊄ more to the score of fourth coin which means 86⊄ +2⊄ = 88⊄. In the same way, the score of sixth coin will be 88⊄ + 2⊄ = 90⊄. The missing numbers are 88⊄, 90⊄.

Count by 5. Write the missing numbers.

Answer:

Explanation:

First coin score is given as 5⊄. If we count by 5⊄, then a 5⊄ should be added to the first coin score to get the second coin which means 5⊄ + 5⊄ = 10⊄. It was given that the score of third coin is 15⊄ which is expected. Similarly, for the fourth coin, we need to add one more 5⊄ to the third coin score which means 15⊄ + 5⊄ = 20⊄. It was given that the score of fifth coin is 25⊄ which is expected. In the same way, the score of sixth coin will be 25⊄ + 5⊄ = 30⊄. The missing numbers are 20⊄, 30⊄.

Count by 5. Start at 50⊄.

Answer:

Explanation:

First coin score is given as 50⊄. If we count by 5⊄, then a 5⊄ should be added to the first coin score to get the second coin which means 50⊄ + 5⊄ = 55⊄. It was given that the score of third coin is 60⊄ which is expected. Similarly, for the fourth coin, we need to add one more 5⊄ to the third coin score which means 60⊄ + 5⊄ = 65⊄. It was given that the score of fifth coin is 70⊄ which is expected. In the same way, the score of sixth coin will be 70⊄ + 5⊄ = 75⊄. The missing numbers are 65⊄, 75⊄.

Count by 10.

Answer:

Explanation:

First coin score is given as 10⊄. If we count by 10⊄, then a 10⊄ should be added to the first coin score to get the second coin which means 10⊄ + 10⊄ = 20⊄. It was given that the score of third coin is 30⊄ which is expected. Similarly, for the fourth coin, we need to add one more 10⊄ to the third coin score which means 30⊄ + 10⊄ = 40⊄. For the fifth coin, we need to add one more 10⊄ to the fourth coin score which means 40⊄ + 10⊄ = 50⊄. It was given that the score of sixth and seventh coin is 60⊄, 70⊄ which is expected. In the same way, the score of eight and nine coin will be 70⊄ + 10⊄ = 80⊄ and 80⊄ + 10⊄ = 90⊄.

Count backyard by 10. Start at 100⊄.

Answer:

Explanation:

First coin score is given as 100⊄. If we count backyard by 10⊄, then a 10⊄ should be subtracted from the first coin score to get the second coin which means 100⊄ – 10⊄ = 90⊄. Similarly, for the third coin, we need to subtract one more 10⊄ from the second coin score which means 90⊄ – 10⊄ = 80⊄. It was given that the score of fourth coin is 70⊄ which is expected. Similarly, for the fifth coin, we need to subtract one more 10⊄ from the fourth coin score which means 70⊄ – 10⊄ = 60⊄. It was given that the score of sixth coin is 50⊄ which is expected. For the seventh coin, we need to subtract one more 10⊄ from the sixth coin score which means 50⊄ – 10⊄ = 40⊄. In the same way, the score of eight and nine coin will be 40⊄ – 10⊄ = 30⊄ and 30⊄ – 10⊄ = 20⊄.
