b)3,5x1i3/4=

c)2i1/2x0,4

d)3/5x1,1=

e)2,4x3/8=

f)4,5x1i2/3

Z góry dzięki za pomoc :)

Answer 1

a) 1 1/2 * 2 2/3 = 3/2*8/3 = 4

b)3,5 * 1 3/4 = 3 5/10 * 1 3/4 = 49/8=6 1/8

c)2 1/2 * 0,4 = 2 1/2 * 4/10 = 1

d) 3/5 * 1,1 = 3/5 * 1 1/10 = 33/50

e)2,4 * 3/8= 2 4/10 * 3/8 = 9/10

f)4,5 * 1 2/3 = 4 5/10 * 1 2/3 = 15/2=7 1/2

g)3/4:1/6 = 3/4 * 6/1 = 9/2 = 4 1/2

h)5 1/2:1 1/3 = 11/2:4/3 = 11/2 * 3/4 = 33/8 = 4 1/8

 

Powinno być dobrze

Answer 2

a) = 3/2 x 5/2 = 15/4 = 3i 3/4

b) = 35/10 x 7/4 = 245/40= 49/8= 6i 1/8 

c) =5/2 x 4/10 = 20/20 = 1

d) = 3/5 x 11/10 = 35/50

e)= 24/10 x 3/8 = 9/10

f) = 45/10 x 5/3 = 15/2 = 7 i 1/2

g) 3/4 : 1/6 = 3/4 x 6/1 = 18/4 = 4 i  2/4 = 4i 1/2

h) 5i1/2 : 1i1/3 = 11/2 x 3/4 = 33/8=4 i 1/8
