trouve les valeurs m , a, t , h réponses en équation 7*m =15 3/4*a=18/24 t*5=3.5 13/3*h=39/24

7×m =15 
 m = 15/7 
 
3/4×a = 18/24 
 a =18/24 ×4/3 = 72/72 =1 

t×5 = 3.5 
t=3.5/5 =7/10 

13/3 ×h =39/24 
 h= 39/24 ×3/13 =3/8

7m = 15
m = 15/7

3/4a = 18/24
3a * 24 = 4 * 18
72a = 72
a = 72/72
a = 1

5t = 3,5
t = 3,5/5
t = 0,7

13/3h = 39/24
13h * 24 = 39 * 3
312h = 117
h = 117/312
h = 0,375
