tolong ya dibantu

Alwiyani 1. 3/4:5/12-1= 36/20 - 1 = 16/20
2. 6:9/6-41/16= 4 - 41/16 = 23/16
3.6/15×16/10:3/16= 96/150 x 16/3 = 1536/450
4. 3/4:9/6+9/18=18/36+9/18 = 36/36 = 1
5.7/14:12/8×9/15=56/168 x 9/15 = 502/2520

wpn 1. $\frac{3}{4}* \frac{12}{5}-1 = \frac{9}{5}- \frac{5}{5}= \frac{4}{5}$
2. $6* \frac{6}{9}= \frac{4}{1}- \frac{41}{16}= \frac{64}{16}- \frac{41}{16}$
= $\frac{23}{16}$ ⇒ $1 \frac{7}{16}$
3. $\frac{6}{15}* \frac{16}{10}= \frac{16}{25}* \frac{16}{3}= \frac{256}{75}=3 \frac{31}{75}$
4. $\frac{3}{4}* \frac{6}{9}= \frac{1}{2}+ \frac{9}{18}= \frac{9}{18} + \frac{9}{18} = \frac{18}{18} =1$
5. $\frac{7}{14} * \frac{8}{12} = \frac{1}{3} * \frac{9}{15} = \frac{1}{5}$

sorry, ya kalo' cara.a krng lengkap. soal.a ada yg aku kurangi, biar g kebanyakan... :)
