Answer :

Answer:

The correct options are,

1.561321 × 10²,

1.56 × 10²,

1.56132 × 10²,

1.5613 × 10²,

1.561 × 10²

Step-by-step explanation:

Given expression,

(151.1 + 2.45 + 3.675) ÷ (0.660 + 0.3470),

= 157.225 ÷ 1.007

= 156.132075472

= 1.56132075472 × 10²

By rounding it to the nearest 6 decimal places

We get,

157.225 ÷ 1.007 ≈ 1.561321 × 10²,

Similarly, by rounding to 5, 4, 3, 2 and 1 decimal places,

Solutions are,

1.56132 × 10², 1.5613 × 10², 1.561 × 10², 1.56 × 10² and  1.6 × 10²  respectively.

Hence, OPTIONS 1, 2, 3, 5 and 7 are correct.
