Question

Several batches of stew were made yesterday. Each batch required 1 and two-thirds pounds of meat. All together, 10 and StartFraction 5 over 6 EndFraction pounds of meat was used. Janice tried to find the number of batches of stew made. Her work is shown below.

10 and StartFraction 5 over 6 EndFraction divided by 1 and two-thirds = StartFraction 65 over 6 EndFraction divided by five halves = StartFraction 65 over 6 EndFraction times StartFraction 2 over 5 EndFraction = StartFraction 130 over 30 EndFraction = 4 and one-third

When she checked the answer by estimating, it did not make sense. What error did Janice make?

    Answer:

    Step 2

    1 2/3 was converted as 5/2 instead of 5/3

    Step-by-step explanation:

    • Each batch = 1 2/3
    • Total = 10 5/6

    Number of batches

    • 10 5/6 : 1 2/3 =
    • 65/6 : 5/3 =
    • 65/6 * 3/5 =
    • 65/10 =
    • 6.5

    Solution by Janice:

    1. 10 5/6 : 1 2/3 =
    2. 65/6 : 5/2 =
    3. 65/6 * 2/5 =
    4. 130/30 =
    5. 4 1/3

    Error made at step 2:

    • StartFraction 65 over 6 EndFraction divided by five halves = StartFraction 65 over 6 EndFraction times StartFraction 2 over 5

    1 2/3 was converted as 5/2 instead of 5/3
