Question

3. Siti and Mary shared $35 in the ratio 4:3. How much money did Siti receive?

Answer 1

Answer:

$20

Step-by-step explanation:

First we will change the ratio so that we are finding how much money Siti receives to the total amount of money.

$4:3 \rightarrow 4:(3+4)=4:7$

Now we can solve for how much money Siti receives using a proportion.

$\frac{4}{7} = \frac{\mbox{money Siti receives}}{35}$

We can see that the denominator increases 5 times, so the numerator must increase 5 times too. This means Siti receives $20.
