MORE DECIMALS PRACTICE

Sometimes it's difficult to calculate expressions involving decimals. 
Learn some useful tips using fractions.

Examples:
m

35 x 0,2 = 35 x 1/5 = 35 : 5 = 7
24 x 0,5 = 24 x 1/2 = 24 : 2 = 12
44 x 0,25 = 44 x 1/4 = 44 : 4 = 11
60 x 0,75 = 60 x 3/4 = 60 x 3 : 4 = 45
---------------------------------------------------------
7 : 0,2 = 7 : 1/5 = 7 x 5 = 35
12 : 0,5 = 12 : 1/2 = 12 x 2 = 24
11 : 0,25 = 11 : 1/4 = 11 x 4 = 44
45 : 0,75 = 45 : 3/4 = 45 x 4/3 = 60
