Miss Allen read for 3/4 of an hour less than the student who read the most. How long sis Miss Allen read for?
kolbaska11 [484]

Answer:

See Explanation

Step-by-step explanation:

Given

Allen = \frac{3}{4}hr less than the most hour

Required

Hours read by Miss Allen

The question is incomplete, as the hours read by each student is not given.

To solve this, I will assume that the longest hours read by a student is x.

So, the expression for Miss Allen will be:

Allen = x - \frac{3}{4}hr

Assume that x = 1hr

The expression becomes

Allen = 1hr - \frac{3}{4}hr

Take LCM and solve

Allen =\frac{4 - 3}{4}hr

Allen =\frac{1}{4}hr
