C:t=2:3
t:h=2:1
multiply first equation by 2 and 2nd by 3
c:t=4:6
t:h=6:3
so
c:t:h=4:6:3
if t is 4 more than c
t is 6 units and c is 4
6-4=2
so 4=2 units
2=1 unit
hollly is 3 units
3*2=6

Answer:
66 sweets
Step-by-step explanation:
Step one:
We are told that the ratio for sharing the sweet is 4:7
that is Jack takes 4 parts and Josh takes 7 paths
If Josh got 18 more
then Let the amount that Jack got be x
so that Josh got x+18
step two:
applying the part to part method, we can find the quantity each of them go
4/7= x/x+18
cross multiply
7x= 4x+72
collect like terms
7x-4x= 72
3x=72
divide both sides by 3
x= 72/3
x= 24
so Jack got 24 sweets
and Josh got 24+18=42 sweets
in all the sweets = 66 sweets
Yeah sometimes I forget these things too.
Just add what’s in the bracket then square it.
(6+1)^2
7^2
= 49
