Answer:
12) 3/5=534 students
13)<em> </em>2151 kg
14)a)7.1 US$
b)total=10.2 US$
Step-by-step explanation:
12)students who had lunch=2/5*890
=356 students
students who did not have lunch=5/5-2/5
=3/5*890
<em> =534 students</em>
14)a)4pens=180 cents
2 books=5.3$
<em> total=7.1 US$</em>
<em> </em>b)5 pens=225 cnets

<em>total=10.2 US$</em>
10)ate=1 over 8
remaining=8/8-1/8
=7/8
after six hours=7/8*2/5
=7 over 20
total ate=1/8+7/20
=14+5 over 40
=19 over 40
remaining=40 over 40 - 19 over 40
= 21 over 40
to dog=21/40 *1/4
=21 over 160
total=19 over 40 +21 over 160
=152+21 over 160
=173 over 160
