Examples on Table of 21
Example 1: By making use of table 21, determine the value of (21 times 4) plus the number 16.
Answer:
Mathematically, (21 times 4) plus the number 16 can be written as:
On utilising the 21 times table,
= 21 × 4 + 16
= 84 + 16
= 100
Therefore, (21 times 4) plus the number 16 is 100.
Example 2: By making use of table 21, check whether the value of (21 times 8) minus the number 18 gives 150.
Answer:
Mathematically, (21 times 8) minus the number 18 gives 150 can be written as:
On utilising the 21 times table,
= 21 × 8 − 18
= 168 − 18
= 150
Therefore, (21 times 8) minus the number 18 is 150. Hence, the statement is correct.
Example 3: Daniel saves 21 dollars every week. Making use of table 21, find the total amount he saves in 12 weeks.
Answer:
Using the 21 times table,
The mathematical statement is:
21 × 12
= 252
Therefore, Daniel saves 252 dollars in 12 weeks.
Example 4: By making use of table 21, determine the value of (21 times 11) plus the number 19.
Answer:
Mathematically, (21 times 11) plus the number 19 can be written as:
On utilising the 21 times table,
= 21 × 11 + 19
= 231 + 19
= 250
Therefore, (21 times 11) plus the number 19 is 250.
Example 5: A shop packs 21 pencils in each box. If 15 boxes are packed, how many pencils are packed in total?
Answer:
Using the 21 times table,
The mathematical statement is:
21 × 15
= 315
Therefore, the shop packs 315 pencils in 15 boxes.
