Answer:
2 : 3
Step-by-step explanation:
Given ratio of sides of 2 similar triangles = a : b , then
ratio of areas = a² : b²
Here by working in reverse
ratio of areas = 4 : 9 , thus
ratio of sides = :
= 2 : 3
Answer:
Step-by-step explanation:
If the third multiple of the whole number is . This means that
is completely divisible by the number
.
So, the whole number is .
The fifth multiple would mean the product of and
