?=8
Step-by-step explanation:
52/ 13 = 4
32/4= ? = 8
Both their ages totaled in 5 (years) - 5 (years)
63 - 5 = 58
Current ages totaled = 58 (years)
Daniela is 23 years older than her daughter (as given above) so...
Current ages totaled (58 years) - How many years Daniela is older than her daughter ( 23 years )
