Question

A dessert has both fruit and yoghurt inside.

Altogether, the mass of the dessert is 185g.
The ratio of the mass of fruit to the mass of yoghurt is 2:3
What is the mass of the yoghurt?

Answer 1

note: f=fruit

y=yoghurt

2:3

f : y

f/y=2/3

=> 3*f=2*y

f=(2*y)/3

we know that f+y=185g

(2*y)/3+y=185g

(2*y+3*y)/3=185g

5*y/3=185

y=(185*3)/5

y=111g

=>the mass of the yoghurt is 111 g
