Answer 1

oblicz.

a)6/15*12/30= 4/25

b)3/7*7/5=3/5

c)7/12*4/7=4/12=1/3

d)3*5/6*24/15=15/6 ·24/15=24/6=4

e)6/13* 2⁸/₉=6/13 ·26/9 =4/3=1⅓

f)2/3*6=12/3=4

g)5/8*6*4/15=30/8 ·4/15 =2/2=1

Answer 2

a)6/15*12/30=2/5 * 4/10 = 2/5 * 2/5 = 4/25

b)3/7 * 7/5=3/1 * 1/5 = 3/5

c)7/12*4/7= 7/3 * 1/7 = 1/3 * 1/1 = 1/3

d)3* 5/6 * 24/15=5/2 * 24/15 = 12/3 = 4

e)6/13*2 8/9= 6/13 * 26/9 = 4/3 = 1 i 1/3

f)2/3*6= 12/3 = 4

g)5/8*6*4/15= 30/8 * 4/15 = 2/2 = 1
