Question

Вычислите:
2 1/3 * 2
4* 1 1/2
1 1/3*9
3/7* 2 1/3
1 1/3* 1 1/2

Answer 1

2 1/3 * 2=7/3*2/1=14/3=4 2/3;//// 4* 1 1/2=4/1*3/2=6;///. 1 1/3*9=4/3*9/1=12;.//// 3/7* 2 1/3=3/7*7/3=1;//// 1 1/3* 1 1/2=4/3*3/2=2

Answer 2

2 1/3*2=4 2/3
4 * 1 1/2=6
1 1/3*9=12
3/7 * 2 1/3 = 3/7 * 7/3= 1
1 1/3 * 1 1/2 = 4/3 * 3/2 = 2
