7b/12=4.2. Which two sides do you times by 12 and divide by 7?
The two sides are "7b/12" and "4.2".
Original equation: 7b/12 = 4,2
Multiply both sides by 12: 12(7b/12) = 12(4.2) [The 12s on the left side cancel.]
Simplify: 7b = 50.4
Divide both sides by 7: (7b)/7 = 50.4/7 [The 7s on the left side cancel.]
Simplify: b = 7.2
Thank you!
