Question

2 1/7 * 1.6 *2/1/3=
6 2/3* (0.25 + 1/5 ) =
3 1/3 - 1/3 * 0.=

0.9 : 1/5 + 1/3 - 3/9 =

Answer 1

a.) 2 1/7 * 1.6 *2/1/3= 15/7 * 1 6/10 * 2/1 : 1/3 = 15/7 * 16/10 * 2/1 * 3/1 = 3/7 * 16/1 * 1/1 * 3/1 = 144/7 = 20 4/7 

b.) 6 2/3* (0.25 + 1/5 ) = 20/3 * (25/100 + 15/10) = 20/3 * (25/100 + 150/100) = 20/3 * 175/100 = 175/15 = 11 10/15 = 11 2/3

c.) 3 1/3 - 1/3 * 0.= 10/3 - 1/3 * 0 = 0 

d.) 0.9 : 1/5 + 1/3 - 3/9 = 9 /10 * 5/1 + 3/9 - 3 /9 = 9/2 = 4 1/2
