We want to divide a number by a decimal number. The calculations are easier if we multiply the divisor and the dividend by the same power of 10 so that the divisor is a whole number. In this case, we will multiply by 100.
13* 100 &= 1300
0.65* 100 &= 65
This means that 13Ă· 0.65 is the same as 1300Ă· 65. Now we will find the exact quotient. We divide, multiply, subtract, and compare as many times as we need.
