Question

if 63.9805 =6a+3/b+9c+8/d+5e Then find the value of 4a+7b+6c+d+3e

Answer 1

Make it expanded form. Keep it equal

60+3+9/10+8/100+5/10000 =4a=3/b+9c+8/d+5e

A=10

B=1

C=1/10

D=100

E=1/10000

4A

=40

7B=7

6C=6/10

D=100

3E=3/10000

Therefore 147.6003

Answer 2

Hey dear,

◆ Answer-

4a+7b+6c+d+3e = 147.6005

◆ Explaination-

We can write,

63.9805 = 6×10 + 3×1 + 9/10 + 8/100 + 0/1000 + 5/10000

Comparing this to 6a+3/b+9c+8/d+5e , we can calculate -

a = 10

b = 1

c = 1/10

d = 100

e = 1/10000

Now, let's calculate

4a+7b+6c+d+3e = 4×10 + 7×1 + 6/10 + 100 + 3/10000

4a+7b+6c+d+3e = 100 + 40 + 7 + 0.6 + 0.0005

4a+7b+6c+d+3e = 147.6005

Hence, vaule of

4a+7b+6c+d+3e = 147.6005 .

Hope this helps you...
