Let's take Yasmine's age as 'k'.

(1) Given that, Yasmine's mom = 4 times as old as Yasmine = 4k (keyword ⇨ times = multiplication)

So, Yasmine's mom = 4 × k

____________

(2) Given that, Yasmine's sister = 10 years older than Yasmine = 10 + k (keyword ⇨ older than = addition)

So, Yasmine's sister = 10 + k
