Question

The diameter of a grain of sand is estimated to be about .0024 inches. Write the estimated diameter of a grain of sand in scientific notation.

Answer 1

2.4 x 10-₃

Explanation:

the numbers with NO zeros should be first and the first number should be turned to a whole so like "2.4". Since there are 3 zeros (including the zero in the whole number place) you would write the 3 as the number in the right corner. And there is a minus sign beside the 3 because the Zeros are first. :)
