Answer:
Noor's age is 12 & Salma's age is 18
Step-by-step explanation:
Noor's age: N
Salma's age: S
: given
: given
: isolate "N"
: substitute the value of N for N to find the value of "S"
: subtract 3 from both sides
≡
: multiply both sides by 2
: add like values
: divide both sides by 3
S = 18
now insert that value into the initial equation:

: subtract 18 from both sides
We are given:
12 counters which are three-fourths of a set of counters, meaning the total number of counters in a set is determined by:
total number of counters in a set = 12/(3/4) = 16 counters
Therefore, we need to draw 16 counters and shade 12 of them to represent the three-fourths of the set.
