=5/8÷(1/4 + 7/8)

=5/8÷9/8

=5/8 * 8/9

=5/9

3.5÷(5/8)×7/4等於多少列脫式計算?

脫式計算

3.5÷(5/8)×7/4

=5.6x7/4

=8.4

3樓:ronin黃是

3.5÷5/8×7/4

=5.6×7/4

=9.8

脫式計算,5/8×7+9÷8/5,15÷(2/3-1/5),6/5×2/15+2/15÷5/4?

4樓:妙酒

5/8×7+9÷

8/5,

=5/8x7+9x5/8

=(7+9)x5/8

=16x5/8

=1015÷(2/3-1/5)

=15÷(10/15-3/15)

=15÷7/15

=225/7

6/5×2/15+2/15÷5/4

=2/15x6/5+2/15x4/5

=2/15x(6/5+4/5)

=2/15x2

=4/15

脫式計算:5/8÷75%- 2/19×38% (3/8+37.5%)÷(2.1-209%) 2.5×125×32

5樓:古德納克

5/8÷75%- 2/19×38%

=5/8×100/75-2/19×38/100=5/6-1/25

=119/150

(3/8+37.5%)÷(2.1-209%)=(0.375+0.375)÷(2.1-2.09)=0.75÷0.1

=0.75×10

=7.5

2.5×125×32

=2.5×32×125

=2.5×4×4×2×5×25

=10×10×100

=10000
