......=7x3/15+7x3/15-1/3
......=21/15+21/15-1/3
......=42/15-1/3
......=42/15-5/15
......=37/15
......=2又7/15

Answer 2

根据题目意思列算式计算，
7/15✘3-1/3+7/15✘3
=7/15✘(3+3)-1/3
=42/15-1/3
=42/15-5/15
=41/15
或者写成2又15分之11，

Answer 3

Answer 4

7/15×3-1/3+7/15×3
=7/15×3(1+1)-1/3
=7/15×6-5/15
=1/15(42-5)
=1/15×37
=37/15

Answer 5

那就是
=7/5+7/5-1/3
=14/5-1/3
=42/15-5/15
=37/15
=2又7/15
