Question

Blake estimated that 130% of 20 is “2.6.” Without doing any calculations, explain to Blake how you know he is wrong. Then after explaining why he is wrong, show the work to estimate correctly.

Answer 1

2.6 is way less than 20 and 130% of 20 has to be greater than 20. The correct answer is 26

Answer 2

100 % represents the actual amount. For e.g. 100 % of 10 is 10 .

So 100 % of 20 have to be 20.

And 130% is more then 100%, therefore the value of 130%, should be more then 2.6 .

So 130% of 20 is 2.6 is wrong .

And to find 130% of 20, we just multiply 130 and 20 and divide by 100 which gives 26 .
