Question

有人会这几道数学题目吗?快快快!!拜托了.急急!!

8/9X-3.2=3.2 (5/6-0.75)*1又1/5除1又4/5 3又1/4*(1.64+1.64+1.64+1.64) 2又3/16除[(7/8-2/3+5/6)*24] 24又9/11除13*[1又1/9+(23.5-23又3/14 快一点,拜托了,过程也要的.急啊!!!谢谢好心人了.真的很急的.

Answer 1

① 8/9 X - 3.2 =3.2
8/9 X =6.4
X =6.4 * 9/8
X =7.2
② （5/6 - 0.75）* 6/5 ÷ 9/5
=（5/6 - 3/4）* 6/5 * 5/9
=1/12 * 2/3
=1/18
③ 13/4 * (1.64+1.64+1.64+1.64)
=13/4 * (41/25 * 4)
=13 * 41/25
=533/25
=21又8/25
④ 35/16 ÷ [(7/8 -2/3 +5/6)*24]
=35/16 ÷ (21 - 16 + 20)
=35/16 ÷ 25
=35/16 * 1/25
=7/80
⑤ 273/11 ÷ 13 * [10/9 + (235/10 - 325/14)]
=273/11 * 1/13 * (100/90 + 2115/90 - 1625/90)
=273/11 * 1/13 * 59/9
=（7*59）/33
=413/33
=12又17/33
