Summands 5215

Divide the number into two summands, which are in the given ratio:
a) 3, 11: 4
b) 5.1 8: 9
c) 1 7: 3
d) 0.42 1: 6

Correct answer:

a1 =  2.2
a2 =  0.8
b1 =  2.4
b1 =  2.7
c1 =  0.7
c2 =  0.3
d1 =  0.06
d2 =  0.36

Step-by-step explanation:

a1=3 11/(11+4)=511=251=2.2
a2=3 4/(11+4)=54=0.8
b1=5.1 8/(8+9)=512=252=2.4
b1=b2=5.1b1=5.12.4=1027=2107=2.7
c1=1 7/(7+3)=107=0.7
c2=1c1=10.7=103=0.3
d1=0.42 1/(1+6)=503=0.06
d2=0.42d1=0.420.06=259=0.36
