Question

Without multiplying, tell whether the product 0.644 x 0.25 will be greater than 1 or less than 1? Explain how you know.

Answer 1

Less than 1

Explanation:

Both the number are less than 1, i.e 0.64 and 0.25.

Hence, the result will always be less than 1 and will be in zeros.

If you write both numbers in fraction, the denominator will be greater than the numerator, hence the resulting fraction will be less than 1.

Hope this helps.

Good luck and thankyou.

Answer 2

Less than 1

Explanation:

As 0.644 and 0.25 are less than 1, then

`0.644=(1)/(p)`

`0.25=(1)/(q)`

where p and q are greater than 1

then

`0.644*0.24=(1)/(p.q)`

But p.q is greater than 1, so 1/(p.q) is smaller than 1
