Answer:

Step-by-step explanation:
We want to find the rational number which is equal to
.
Let
....eqn(1)
Multiply both sides by 10
.....eqn (2)
Subtract eqn (1) from eqn (2)


Divide both sides by 9.

Answer:
f = 1
Step-by-step explanation:
Use the method of cross- multiplication
=
⇒ ad = bc, thus
20f = 5(f + 3) ← distribute
20f = 5f + 15 ( subtract 5f from both sides )
15f = 15 ( divide both sides by 15 )
f = 1
Answer:
m = 32g
Step-by-step explanation:
The proportion between m and g can be written ...
m = kg
where k is the constant of proportionality.
__
We can find its value by dividing by g:
k = m/g
Using any pair of corresponding values from the table, we find ...
k = 64/2 = 32
The relationship between m and g can be expressed by the equation ...
m = 32g
