Question

Jamar helped in a community garden for 21/10 hours this week that was 2 4/5 equal length shifts because Ja’Marr shop early one day when it started train what does 21 over 10÷2 and 4/5 representing the situation

Answer 1

Answer: The expression 21/10 ÷ 2 4/5 represents the number of hours Jamar worked per shift in the community garden, given that he worked for a total of 21/10 hours over 2 4/5 shifts.

To simplify this expression, we need to convert the mixed number 2 4/5 to an improper fraction:

2 4/5 = (2 x 5 + 4)/5 = 14/5

Now we can rewrite the expression as:

21/10 ÷ 14/5

To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction:

21/10 x 5/14 = 3/4

Therefore, Jamar worked an average of 3/4 hours per shift in the community garden.
