A. Jessie's error is in the step where they multiplied 17/5 and 3/10. The correct operation should have been a division, not a multiplication.
B. To correctly solve the problem, we divide 17/5 by 3/10. To divide fractions, we need to find the reciprocal of the divisor (3/10) and multiply it with the dividend (17/5).
Reciprocal of 3/10 = 10/3
Now, we multiply 17/5 and 10/3:
17/5 * 10/3 = (17*10)/(5*3) = 170/15 = 34/3
So, the correct answer is 34/3, or 11 1/3.
Jessie was given the problem 3 2/5 divided by 3/10 = to solve. Jessie's work looks like this:
3 2/5 divided by 3/10 =
17/5 divided by 3/10 =
17/5 x 3/10 = 51/50
51/50 = 1 1/50
