Tips for Memorizing a Table of 51.
- One of the most common tricks students use is writing down the multiplication table of 51 from 1 to 20. Example: One time fifty-one is 51, Two times fifty-one is 102, Three times fifty-one is 153 and so on.
- The second easy trick is skip counting, which is the practice of counting forward from 0. We repeatedly add the same number to the last number to skip counting. For example, here, we will count adding 0 to 51. So, 0 + 51= 51, 51 + 51 = 102, 51 + 102 = 153 and so on.
- Students can use another trick, writing down the multiplication table of 1 with 50 and adding their sum. Take a look at the table shown below.
Table of 1 | Table of 50 | On Addition we get | |
1 x 1 = 1 | 50 x 1 = 50 | + | 51 |
1 x 2 = 2 | 50 x 2 = 100 | + | 102 |
1 x 3 = 3 | 50 x 3 = 150 | + | 153 |
1 x 4 = 4 | 50 x 4 = 200 | + | 204 |
Therefore, we get the multiples of 51 by this method.
Solved Examples
1)Ana jogs 5 miles per day. How many miles can Ana jog in 51 days?
Solution:
Number of miles Ana jogs per day = 5
Number of miles covered by Ana in 51 days = Number of miles Ana jogs per day x 51
=> 5 x 51 = 255
Therefore, the total miles traveled after 51 days by Ana is 255.
Example 2: A restaurant prepares 15 kg of Rice a day. How many kilos of Rice will be prepared in 51 days at the restaurant?
Solution:
Rice prepared in a day = 15 kg.
Rice prepared in a day = Rice prepared in a day x 51 days.
=> 15 x 51 = 765 kg,
Therefore, 765 kg of Rice will be prepared in 51 days at the restaurant.
Example 3: Lara spends $16 per day on utilities. How much money will she spend in 51 days?
Solution:
Amount spent by Lara in 1 day = $16
Amount spent by Lara in 51 days = Amount spent by Lara in 1 day x 51
=> 16 x 51 = 816
Therefore, $816 will be spent by Lara in 51 days.
