Calculate the following questions in a simple way 15－5÷12－7/12 2－1/4－1/3－3/4 5/8－（5/8－1/2） 1/5×37%＋4/5×37% 1/6÷11/24－3/8×4//11 68－7.5＋32－2.5

15－5÷12－7/12
=15－5/12－7/12
=15－(5/12+7/12)
=15-1
=14
2－1/4－1/3－3/4
=2－1/4－3/4－1/3
=2-(1/4+3/4)－1/3
=2-1-1/3
=1-1/3
=2/3
5/8－（5/8－1/2）
=5/8-5/8+1/2
=1/2
1/5×37%＋4/5×37%
=(1/5＋4/5)×37%
=37%
1/6÷11/24－3/8×4/11
=1/6*24/11－3/8×4/11
=4/11－3/8×4/11
=4/11(1－3/8)
=4/11*5/8
=5/22
68－7.5＋32－2.5
=68＋32－7.5－2.5
=100－(7.5+2.5)
=100-10
=90

How to simplify the operation of the following questions
5 out of 7 + 2 out of 7 + 1 out of 6 + 1 out of 15 × (1 out of 3 + 1 out of 12) 1 out of 4 ^ (5 out of 3-13-8 out of 13) 4 out of 9 ^ [5 out of 6 - (1 out of 6 + 3 out of 3)]

5 / 7 + 2 / 7 + 1 / 6 = 5 / 7 + 2 / 7 + 1 / 6 = 1 + 1 / 6 = 1 and 1 / 615 × (1 / 3 + 1 / 12) = (1 / 15) (4 / 12 + 1 / 12) = (1 / 15) (5 / 12) = (1 / 3) (1 / 12) = 1 / 364 / 1 △ 3-13 / 5-13 / 8) = (1 / 4) / [3 - (5 / 13 + 8 / 13)] = (1 / 4) / [3-1] = (1 / 4) / [2 = 1 / 89

Use simple calculation to calculate the following questions

Simple calculation of the following topics
4.4+4.4×12+13×5.6

4.4+4.4×12+13×5.6
=4.4(1+12)+13*5.6
=4.4*13+13*5.6
=13*（4.4+5.6）
=13*10
=130
