Answer:
4 11/20
Step-by-step explanation:
Using bidMAs Multiplication comes first before addition
2/5 * 7/6 = 14/30
7/6 * 7/2 = 49/12
Make denominators equal
14/30 * 2 = 28/60
49/12 * 5 = 245/60
Then add
28/60 + 245/60 = 273/60
Finally convert improper into mixed fraction
4 11/20

Step-by-step explanation:
GP = 1/2 , 1/4 , 1/8 , 1/16
1st) the common ratio is (1/4 : 1/2 ) = 1/2, so r =1/2
2nd) the sum of a GP is:
S= a(1-rⁿ)/(1-r)
S=(1/2).[1-(1/2)⁴]/(1-1/2) = 15/16
