The problem on page 4 1 of the math exercise book for the fifth grade in primary school needs to be solved urgently! ! ! The topic is below.
1.① Divide by 8 = 2/3 ② Divide by 15 = 3/2 ③ Divide by 5 = 65438+32/5 ④ Divide by 125 = 5/8.
2. ① 7 of18 times 5 of 90 = 35 of 65438 times 3 of 00 times 9 of 90 = 27 of 90.
②2 4/9 times 5/5=2 20/45, and 2 3/5 times 9/9=2 27/45.
③ 1 and 10 7 times 6= 1 and 60 42, 15438+0 times 4 = 6044,20.
