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.
