We can express this as a ratio. 4 balls :8 caps.
Then simplify. 1 ball: 2 caps.
We have to make caps equal to 6, so multiply by 3. For consistency, we need to multiply the number of balls by 3 too.
3 balls: 6 caps.
So Malcolm needs 3 balls of wool.

Answer:
Step-by-step explanation:
Now sum of infinite series is
a
1
−
r
and if first three term are removed, fourth term becomes the first term i.e. first term becomes
a
r
3
and
sum of infinite series becomes
a
r
3
1
−
r
As
a
1
−
r
=
27
×
a
r
3
1
−
r
27
r
3
=
1
or
r
3
=
1
27
and
r
=
1
3
and hence
Common ratio is
1
3
Answer: There is no picture. What do you need explain in detailed?
Combine the terms with j, so -7j+3 would be left.
