Words learned: 5.4m=378 According to the nature of the equation: the left and right sides of the equation are multiplied or divided by a number (not 0) at the same time, and the size of the equation remains unchanged. 5.4×m on the left is 5.4m. Divide by 5.4 to leave m, and divide by 5.4 on the right. therefore

5.4m=378

m=378÷5.4

m=70

Of course, you can do this if you haven't learned fractional division.

5.4m=378 (both sides are multiplied by 10 at the same time, and 5.4 becomes 54, which is an integer division).

54m=3780

m=3780÷54

m=70
