Answer:

Step-by-step explanation:
The given equation is :
d = 5x + 10xf
We need to solve the above equation for x.
Taking x common from RHS,
d=x(5+10f)
Dividing both sides by (5+10f),

Hence, this is the required value of x.
We have to divide 9/10 by 3/12.
if we divide by a fraction, we can instead multiply by it's inverse:

so now we count:

so we can cut exactly 3 pieces!
