Answer:
Step-by-step explanation:
We have,
The recipe need 
cups of flour.
Also, the chef is making the amount which is 
of the recipe.
Thus, the total amount of the flour required will be,
= cups.
Hence, the chef should use cups of flour.
This reduces to a simple addition problem.
You walk 1/6 or one sixth of a mile, then 1/3 or one third of a mile.
The result is 1/3 + 1/6.
Using basic properties of fractions, we can substitute 2/6 for 1/3:
2/6 + 1/6 = 3/6.
3/6 is three sixths, which is exactly 1/2.
So in total, you walked 1/2 miles.

This is a matter of multiplication using scientific notation. First, multiply the mantissas
3.5 * 6.6 = 23.1
Then add the exponents
-2 + 20 = 18
So we initially have 23.1x10^18
But 23 is too large (the number has to be greater than or equal to 1 and less than 10). So divide the 23.1 by 10 and add 1 to the exponent, getting
2.31x10^19
Then since the least accurate value we have for input has only 2 significant digits, round the result to 2 significant digits, getting
2.3x10^19 kg</span>
