Answer:
36 personas
Step-by-step explanation:
las 2/5 partes q completaron secundaria tambien finalizaron primaria
con lo cual el tercio que estudio primaria esta dentro del grupo de personas que estudiaron
60*2/5 = 24
24 personas estudiaron
60-24=36
Answer:
Equivalent ratios
20 = 40 = 60 = 80 and so on....
15 = 30 = 45 = 60 and so on.....
Both include 60
39=3m-15
39+15=3m
54=3m
54/3=3m/3
m=18
I honestly think it has two solutions
X=-1
X=6
Step-by-step explanation:
100% = 4.25
1% = 100%/100 = 4.25/100 = 0.0425
how many % are 3.4 ?
we find this by calculating how often 1% (0.0425) fits into 3.4.
3.4 / 0.0425 = 80 %
