Estimating 5 and 9/10ths times 2 and 2/3rds might be done by considering that 5 and 9/10ths is about 6, and 2 and 2/3rds is somewhat less than three. Six times three is eighteen, but it's less than that by a couple or three, so the answer is about fifteen or sixteen.
Estimation is about making broad strokes. Two and four fifths is very close to three. Four times three is twelve and 1/3 times 3 equals 1. Thus the estimated answer is 13.
6 and one third
They add up to: 28/15
1/4 x 16/5 = 16/20 = 4/5 (four fifths)

negative fourth fifths is less than negative one-third

The answer is seven fifteenths.Hope it helped!

Hint: four-fifths of "seven" is "even". Now how is one-third of one-half "el"?
One third of three fifths is one fifth.
1/3 X 24/5= 8/5
