Question

Asma was asked to compare the following two numbers.

A = 6.212 x 108 and B = 4.73 x 10
She says,
“6.212 is bigger than 4.73 so A is bigger than B."
Is Asma correct?
You must give a reason for your answer

Answer 1

Yes Asma is correct because,

Even if we round off both no. to the nearest whole number we get 6 and 5 respectively.
That’s how we can also know which no. is bigger. The bigger no. is 6.212 and if we solve the equation, we get the answers
670.896 and 47.3 respectively.
So A is bigger than B in the two aspects mentioned above.

Hope this helped and have a nice day : )
