Jiangsu Education Press sixth grade volume I mathematics supplementary exercise on a problem, online and so on The last question on page 47 of the supplementary exercises of mathematics in Volume 1 of grade 6 of Jiangsu Education Press, to calculate the formula, thank you. In addition, there are () expectation and () fight, please answer There is a two digit number. The number in one digit is two thirds of the number in ten digit. If you subtract three from a number in ten, it is equal to a number in one. What's the two digit number
Let X be the one digit and 3 / 2x be the ten digit
3/2x-x=3
1/2=3
Bit x = 6
Ten digits: 6 * 3 / 2 = 9
9*10+6=96
