Answer:
58% of 121 by using 10% is 70.18.
Step-by-step explanation:
Given : 58% of 121.
To find : estimate 58% of 121 by using 10%.
Solution : We have given 58%
Estimate of 58% is 60%
We need to use 10%
We can write 60% as 6 times of 10%
Since , 10% of 121
= 12.1
60% = 6 times of 10%
Plugging the values
60% == 6 times of 12.1
6 *12.1 = 72 .6
To take this further, 58% is 2% less than 60%, or 2 times 1%. 1% of 121 is 1.21.
72.6 - (1.21 * 2) = 72.6 - 2.42 = 70.18
Therefore, 58% of 121 by using 10% is 70.18.
