a baker has 20 pounds of sugar. He uses 3/4 of the sugar to bake muffins. How many sugar does he have left?

Answers

Answer 1

Answer:

This is a wonderfully easy problem. So, you start off by dividing the pounds of sugar by the denominator which is 4. So:

20 / 4 = ?

Then you that product and multiply it by the numerator, which is 3 in this case and you get your answer.

Answer 2

Answer: If 20 is 100% then 20 divided by 4 equals 5 so 20 lbs. - 5 lbs. = 15 lbs. the baker has 15 pounds of sugar left.

3.82e+7 in standard form explain

Answers

" e+7 " means the same thing as " x 10⁷ ".

They both mean "move the decimal point 7 places that way ===> ."

So take the 3.82 and do that to it.

If there aren't enough places to move the decimal point far enough,
then add some zeros onto the end of the 3.82 before you move
the point.
