Question

Which choice shows the best estimate of the product 0.52×695

5×600

1/2×700

50×700

1×1,000

Answer 1

B is the correct answer

Answer 2

1/2×700

Explanation:

Here, the given expression is,

`0.52* 695`

Since, we round a number to the nearest number,

Also,
`(1)/(2)=0.50`

That is, 0.50 is nearer to 0.52 than 5, 50, 1.

So, the best estimation of 0.52 from the given option is
`(1)/(2)`

Now, 700 is nearer to 700 than 600 and 1000,

Thus, 700 is the best estimation of 695 from the given options,

Hence, the best estimation of the product 0.52×695 would be 1/2×700.
