Answer:
Sister = 15 years old
Brother = 12 years old
Step-by-step explanation:
Right now, if the brother is B years old and the sister is S years old, B = (4/5)S because the ratio from brother to sister is 4:5, so if one unit is X, B = 4X and S = 5X
Three years ago, the brother was B-3 years old and the sister was S-3 years old. Keeping one unit as X, we have
B = 3X
S = 4X
B-3 = (3/4)(S-3)
Therefore, we have a system of equations
B = (4/5)S
B-3 = (3/4)(S-3)
Substitute (4/5)S for B into the second equation to only have one variable
(4/5)S - 3 = (3/4)(S-3)
(4/5)S - 3 = (3/4)S - 9/4
add 3 to both sides and subtract (3/4)S from both sides to isolate the variable and its coefficient
(1/20)S = 3/4
multiply both sides by 20 to isolate the S
S = 15
B = (4/5)S = 12

Answer:
reflection then transition
Step-by-step explanation:
because ummm for it to get to one it is reflected then to get to 3 it is transitioned
Answer:
Let me take 2,3,3 be 2x, 3x, 3x
Colin = 2x
Natasha = 3x
Angad = 3x
The equation forms to find out the value of x
2x + 3x + 3x = 48
=> 8x = 48
=> x = 48/8
=> x = 6
So share of Colin = 2x = £(2×6) = £12
Share of Natasha = 3x = £(3×6) = £18
share of Angad = 3x = £(3×6) = £18
For proof
£12 + £18 + £18 = £48
Hope it helps
