solve equation 3(k4.8)=0.7(k6.9) show steps to solve this please

math 
Jennifer,
3(k4.8)=0.7(k6.9)
3*k3*4.8=0.7*k0.7*6.9
3k  14.4 = 0.7k  4.83
Subtracting 0.7k from each side:
3k 0.7k  14.4 = 0.7k  0.7k  4.83
2.3k  14.4 = 4.83
Adding 14.4 to each side
2.3k = 9.57
Dividing each side by 2.3:
k = 4.16
