Question

Neuma had a container that held StartFraction 9 Over 54 EndFraction of a kilogram of rainbow sprinkles. She divided the sprinkles evenly to put on top of the 9 servings of ice cream that she was making for her friends at the sleepover. To determine the weight of each serving, Neuma performed the calculations below. StartFraction 9 Over 54 EndFraction divided by 9 = StartFraction (9 divided by 9) Over (54 divided by 9) = one-sixth She concluded that each serving weighs One-sixth of a kilogram. What is Neuma's error? Neuma should have multiplied by 54, not divided. Neuma should have multiplied by 9, not divided. Neuma should have only divided 9 by 9, not 54 by 9. Neuma should have only divided 54 by 9, not 9 by 9.

Answer 1

Answer:

Neuma should have only divided 54 by 9, not 9 by 9.

Step-by-step explanation:

The amount of rainbow sprinkles in the container$= \frac{9}{54}$ kg.

As she divided the sprinkles evenly to put on top of the 9 servings of ice cream and her calculations to get weight of each serving is

$\frac{9}{54}\div 9$

$=\frac{9\div9}{54\div9}$ (this is wrong step)

$=\frac{1}{6} kg$

The correct calculation is as follows

$\frac{9}{54}\div 9$

$=\frac{9}{54}\times \frac 1 9 =\frac{9}{54\div9}$ (corrected step)

$=\frac{1}{54} kg.$

Hence, Neuma should have only divided 54 by 9, not 9 by 9.
