Answer 2

32 Children were absent

Step-by-step explanation:

GIVEN

Total Children = 160

Present = 4/5

___________________________

TO FIND

How many were absent

___________________________

Let's find the percent of 4/5

Percent = 4/5 × 100

Percent = 0.8 × 100

Percent = 80

Percent = 80

80% of Children was present

___________________________

Let's find the number of Children present and number of Children absent

Present Children

Percent = ( Part Value / Total Value ) × 100

Part Value = ( Percent / 100 ) × Total Value

Part Value = 80 / 100 × 160

Part Value = 0.8 × 160

Part Value = 128

Present Children = 128

Absent Children = Total Children - Present Children

Absent Children = 160 - 128

Absent Children = 32

32 Children were absent
