abc987

the answer is A.1/2×800

Answer:

Step-by-step explanation:

We are given to ask a product of 0.51x783

If we want to find out the product without actual multiplication we can round off both factors to nearest and do

0.51 is very near to \(0.5 = 1/2\)

783 rounded off would be 800 since \(second digit >5\)

So the product would be approximately

\(\frac{1}{2} *800\)

i.e. option A

Option B is incorrect because 1000 is very far from 783

C is wrong because 700 is not correct round off of 783

D is wrong since 50 is not round off value of 0.51
