a.1/2 × 800

b.1 × 1,000

c.5 × 700

d.50 × 800

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

783 rounded off would be 800 since

So the product would be approximately

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

after simplifying it i got: -36.25 as my answer. hope that !
