Answer:

  9       :      4

total amount = $520

add the two parts in the ratio(9+4) to get the total parts.

9 + 4 = 13parts .   so, 13 parts = 520.

what about 9 and 4?

13 = 520

9 = ?

9 × 520/13 = 360

4 × 520/13 = 160.

Answer 2

Answer:

Savings = $ 360

Spending = $ 160

Step-by-step explanation:

Savings: spending = 9 : 4

Total part = 9 + 4 = 13

Part of saving = 9/13

Savings = (9/13) of 520

            $=\frac{9}{13}*520\\\\=9*40$

           = $ 360

Spending = 520 - 360 = $ 160
